Keeta Network MCP Server

A dynamic, self-describing MCP (Model Context Protocol) server that gives AI agents native access to the Keeta Network — a Layer 1 blockchain built for payments, asset transfers, cross-chain interoperability, and compliance-ready financial infrastructure.

This server is designed for autonomous agent use. It does not require updates when the Keeta SDK is expanded — new SDK methods are automatically discoverable at runtime through built-in introspection tools.

What is Keeta Network?

Keeta is a Layer 1 blockchain purpose-built for the global financial system:

  • 10M+ TPS with 400ms settlement — faster than any traditional payment rail
  • Native tokenization — create tokens with built-in rules (transfer restrictions, allowlists, time locks) enforced at protocol level
  • Atomic swaps — instant exchange between any two assets on the network
  • Anchors — regulated entry/exit points that bridge Keeta to external systems (SWIFT, ACH, FedNow, other blockchains like Base/Ethereum). Any foreign asset tokenized on Keeta is 1:1 backed and can be returned to its native chain at any time
  • Built-in compliance — X.509 certificate-based identity for KYC/AML without storing PII on-chain
  • Permissions system — granular per-account and per-token access controls (ACCESS, ADMIN, SEND, RECEIVE, etc.)
  • DAG architecture — each account has its own chain, enabling parallel transaction processing
  • Multiple signature algorithms — ECDSA SECP256K1, SECP256R1 (WebAuthn), ED25519

Token: KTA (used for transaction fees and governance) Networks: main (production), test (development with free faucet)

Quick Start

Install

git clone <this-repo>
cd kta-mcp
npm install
npm run build

Configure (Recommended: Both MCP Servers)

Agents building on Keeta should use two MCP servers together:

  1. keeta-docs — The Keeta documentation MCP (hosted by GitBook) provides searchable protocol knowledge: architecture, anchor system, SDK references, tutorials
  2. keeta-sdk — This server provides the tools to execute operations on the network

Claude Code

# Add the Keeta docs MCP (read the docs, understand the protocol)
claude mcp add --transport http keeta-docs https://docs.keeta.com/~gitbook/mcp

# Add the Keeta SDK MCP (execute operations on the network)
claude mcp add keeta-sdk node /absolute/path/to/kta-mcp/build/index.js

Claude Desktop / Other MCP Clients

{
  "mcpServers": {
    "keeta-docs": {
      "type": "url",
      "url": "https://docs.keeta.com/~gitbook/mcp"
    },
    "keeta-sdk": {
      "command": "node",
      "args": ["/absolute/path/to/kta-mcp/build/index.js"]
    }
  }
}

Why both? The docs MCP gives agents the knowledge to build correctly (protocol rules, anchor architecture, metadata formats, compliance requirements). The SDK MCP gives agents the tools to execute. Using only the SDK server without understanding the protocol is like having a hammer without knowing what you're building.

Development

npm run dev    # Run with tsx (no build step)
npm run build  # Compile TypeScript
npm start      # Run compiled output

Architecture: Dynamic & Future-Proof

This MCP server uses a discover-then-execute pattern instead of hardcoded tools. When the Keeta SDK adds new methods, classes, or features, agents discover them automatically without any server updates.

Smart Argument Resolution

Arguments passed to execution tools are automatically resolved based on prefixes:

| Pattern | Resolves To | Example | |---|---|---| | keeta_abc123... | Account.fromPublicKeyString(...) | Token/account addresses | | BIGINT:50000 | BigInt(50000) | Token amounts, supplies | | PERM:ACCESS,ADMIN | new Permissions(['ACCESS','ADMIN']) | Permission sets | | ALGO:TOKEN | AccountKeyAlgorithm.TOKEN | Key algorithm enums | | ADJUST:SET | AdjustMethod.SET | Permission adjustment methods | | OP:SEND | OperationType.SEND | Block operation types | | BUFFER_B64:aGVsbG8= | Buffer.from('aGVsbG8=','base64') | Binary data | | Plain values | Pass through unchanged | Strings, numbers, booleans, objects |

Agent Workflow Guide

This section describes the recommended workflow for an AI agent using this MCP server. Follow these patterns for any Keeta operation.

Step 0: Read the Documentation (keeta-docs MCP)

Before writing any code, use the Keeta docs MCP server to understand the protocol:

# Via the keeta-docs MCP server (https://docs.keeta.com/~gitbook/mcp):
# - Search for "anchors" to understand the anchor system
# - Search for "block operations" to understand transaction types
# - Search for "permissions" to understand access control
# - Search for "certificates" to understand KYC/identity
# - Search for "tokenization" to understand native token creation

The docs MCP provides full access to https://docs.keeta.com/ — architecture guides, anchor system documentation, SDK references, and tutorials. This is essential context for building anything beyond basic transfers.

You can also read the keeta://docs/mcp-config resource from this server for setup details and key documentation links.

Step 1: Discover What's Available

Introspect the SDK to understand current capabilities:

keeta_list_sdk_methods({ target: "AnchorCatalog" }) → all anchor services & lib modules
keeta_list_sdk_methods({ target: "Client" })        → read-only methods
keeta_list_sdk_methods({ target: "UserClient" })     → authenticated methods
keeta_list_sdk_methods({ target: "Builder" })        → builder/batch methods
keeta_list_sdk_methods({ target: "Account" })        → account utilities + enums
keeta_list_sdk_methods({ target: "Block" })          → block types + operation types
keeta_list_sdk_methods({ target: "Config" })         → network configuration

Step 2: Create an Account

keeta_generate_seed()
→ { seed: "A1B2C3..." }

keeta_derive_account({ seed: "A1B2C3...", index: 0 })
→ { address: "keeta_abc123...", algorithm: "SECP256K1", index: 0 }

Step 3: Fund It (testnet)

keeta_request_test_tokens({ address: "keeta_abc123..." })
→ { status: "success", currentBalance: "5000000000000000000" }

Step 4: Perform Operations

Read-only queries (no account needed):

keeta_client_execute({
  network: "test",
  method: "getAccountInfo",
  args: ["keeta_abc123..."]
})

keeta_client_execute({
  network: "test",
  method: "getAllBalances",
  args: ["keeta_abc123..."]
})

Authenticated operations:

keeta_user_client_execute({
  network: "test",
  seed: "A1B2C3...",
  accountIndex: 0,
  method: "allBalances",
  args: []
})

keeta_user_client_execute({
  network: "test",
  seed: "A1B2C3...",
  method: "generateIdentifier",
  args: ["ALGO:TOKEN"]
})

Read UserClient properties:

keeta_user_client_execute({
  network: "test",
  method: "GET_PROPERTY",
  args: ["baseToken"]
})

Step 5: Batch Operations with Builder

The builder pattern is the most powerful way to perform multiple operations atomically:

keeta_builder_execute({
  network: "test",
  seed: "A1B2C3...",
  accountIndex: 0,
  operations: [
    {
      "method": "setInfo",
      "args": [{
        "name": "USDT",
        "description": "Tether USD on Keeta",
        "metadata": "eyJkZWNpbWFsUGxhY2VzIjo2fQ==",
        "defaultPermission": "PERM:ACCESS"
      }],
      "options": { "account": "keeta_token_address..." }
    },
    {
      "method": "modifyTokenSupply",
      "args": ["BIGINT:1000000000000"],
      "options": { "account": "keeta_token_address..." },
      "computeAfter": true
    },
    {
      "method": "send",
      "args": ["keeta_recipient...", "BIGINT:500000000", "keeta_token_address..."]
    }
  ],
  autoPublish: true
})

Key builder details:

  • computeAfter: true forces block computation after that operation (important when later operations depend on earlier ones, e.g., minting supply before sending tokens)
  • options is passed as the final argument — commonly { account: "keeta_..." } to target a specific token/identifier
  • autoPublish: true (default) calls computeBlocks() and publish() after all operations

Common Task Recipes

Create a Token

1. keeta_generate_seed() → seed
2. keeta_derive_account({ seed, index: 0 }) → ownerAddress
3. keeta_request_test_tokens({ address: ownerAddress })
4. keeta_user_client_execute({ network: "test", seed, method: "generateIdentifier", args: ["ALGO:TOKEN"] }) → tokenAddress
5. keeta_builder_execute({
     network: "test", seed,
     operations: [
       { method: "setInfo", args: [{ name: "MYTKN", description: "My Token", metadata: "<base64 of {decimalPlaces:6}>", defaultPermission: "PERM:ACCESS" }], options: { account: tokenAddress } },
       { method: "modifyTokenSupply", args: ["BIGINT:1000000000000"], options: { account: tokenAddress }, computeAfter: true },
       { method: "send", args: [ownerAddress, "BIGINT:100000000", tokenAddress] }
     ]
   })

Send Tokens

keeta_builder_execute({
  network: "test", seed,
  operations: [
    { method: "send", args: ["keeta_recipient...", "BIGINT:1000000", "keeta_token..."] }
  ]
})

Atomic Swap

keeta_user_client_execute({
  network: "test", seed,
  method: "createSwapRequest",
  args: [{
    from: { account: "keeta_sender...", token: "keeta_tokenA...", amount: "BIGINT:1000" },
    to: { account: "keeta_counterparty...", token: "keeta_tokenB...", amount: "BIGINT:500" }
  }]
})

FX Swap via Anchor

1. keeta_anchor_execute({ network: "test", subtarget: "service", serviceName: "FX", method: "getQuotes", args: [{ from: "keeta_kta...", to: "$USDC", amount: "BIGINT:1000000", affinity: "from" }] })
2. Use returned quote to execute the exchange

Update Permissions

keeta_user_client_execute({
  network: "test", seed,
  method: "updatePermissions",
  args: ["keeta_principal...", "PERM:ADMIN,ACCESS", null, "ADJUST:SET"],
  // optional: pass { account: "keeta_target..." } to target a specific token
})

keeta_anchor_execute({
  network: "test",
  subtarget: "lib",
  libModule: "Resolver",
  method: "getRootMetadata",
  args: []
})

KYC Identity Verification

// Discover KYC methods first
keeta_list_sdk_methods({ target: "AnchorKYCClient" })

// Start a KYC verification request
keeta_anchor_execute({
  network: "test", seed, subtarget: "service", serviceName: "KYC",
  method: "createVerification",
  args: [{ account: "keeta_user...", countryCodes: ["US"] }]
})

// Get supported countries
keeta_anchor_execute({ network: "test", subtarget: "service", serviceName: "KYC", method: "getSupportedCountries", args: [] })

Cross-Chain Asset Movement

// Find providers for a specific asset transfer
keeta_anchor_execute({
  network: "test", seed, subtarget: "service", serviceName: "AssetMovement",
  method: "getProvidersForTransfer",
  args: [{ asset: { token: "keeta_usdc..." }, from: { location: "keeta" }, to: { location: "base" } }]
})

// Provider methods (after getting a provider): initiateTransfer, getTransferStatus,
// createPersistentForwardingAddress, listForwardingAddresses, listTransactions, shareKYCAttributes

Username Management

// Resolve a username to an account
keeta_anchor_execute({
  network: "test", subtarget: "service", serviceName: "Username",
  method: "resolve",
  args: ["alice@provider"]
})

// Search usernames
keeta_anchor_execute({
  network: "test", subtarget: "service", serviceName: "Username",
  method: "search",
  args: [{ search: "alice" }]
})

// Claim a username (requires funded account)
keeta_anchor_execute({
  network: "test", seed, subtarget: "service", serviceName: "Username",

  args: ["BUFFER_B64:aGVsbG8gd29ybGQ="]
})

// Parse a Keeta URI
keeta_anchor_execute({
  network: "test", subtarget: "lib", libModule: "URI",
  method: "parseKeetaURI",
  args: ["keeta://..."]
})

Building an Anchor (Agent Guide)

An anchor bridges the Keeta blockchain to an external system (another blockchain, a bank, a payment processor). Here's how an agent can build one:

What an Anchor Does

  1. Holds liquidity — the anchor operator's account holds tokens on both sides
  2. Provides FX quotes — tells users what exchange rate they'll get
  3. Executes atomic swaps — uses Keeta's native swap mechanism to guarantee both sides complete
  4. Exposes HTTP endpoints — getEstimate, getQuote, createExchange, getExchangeStatus

Anchor Architecture

External System (e.g., Base chain)
        ↕ (bridge logic you build)
Anchor FX HTTP Server
  ├── /api/getEstimate        → estimate conversion rate
  ├── /api/getQuote           → firm quote with provider signature
  ├── /api/createExchange     → execute the swap atomically
  └── /api/getExchangeStatus  → check swap status
        ↕ (Keeta SDK)
Keeta Network (native atomic swaps)

Steps to Build an Anchor

  1. Create anchor operator account — generate seed, derive account, fund it
  2. Create or identify token pairs — the tokens being swapped (e.g., KTA ↔ USDC)
  3. Fund liquidity — ensure the operator account holds enough of both tokens
  4. Build an FX HTTP server — use @keetanetwork/anchor SDK's KeetaNetFXAnchorHTTPServer class, providing your getConversionRateAndFee callback
  5. Register anchor metadata — publish on-chain metadata with setInfo() including the currency map and FX service endpoints
  6. Test — use the FX client tools to get quotes and execute swaps against your anchor

Registering Anchor Metadata On-Chain

keeta_user_client_execute({
  network: "test", seed,
  method: "setInfo",
  args: [{
    name: "MY_ANCHOR",
    description: "My Custom FX Anchor",
    metadata: "<use keeta_anchor_execute with subtarget 'metadata', method 'formatMetadata'>"
  }]
})

The metadata includes:

  • currencyMap — maps human-readable codes ($KTA, $USDC) to token addresses
  • services.fx.<ProviderName> — defines available conversion pairs and API endpoint URLs

Format Anchor Metadata

keeta_anchor_execute({
  network: "test",
  subtarget: "metadata",
  method: "formatMetadata",
  args: [{
    version: 1,
    currencyMap: { "$KTA": "keeta_kta...", "$USDC": "keeta_usdc..." },
    services: {
      fx: {
        MyProvider: {
          from: [{ currencyCodes: ["keeta_kta..."], to: ["keeta_usdc..."] }],
          operations: {
            getEstimate: "https://my-anchor.com/api/getEstimate",
            getQuote: "https://my-anchor.com/api/getQuote",
            createExchange: "https://my-anchor.com/api/createExchange",
            getExchangeStatus: "https://my-anchor.com/api/getExchangeStatus/{exchangeID}"
          }
        }
      }
    }
  }]
})

SDK Discovery Targets

Core SDK

| Target | What It Exposes | When To Use | |---|---|---| | Client | Read-only methods: getAccountInfo, getBalance, getAllBalances, getHeadBlock, getBlock, getHistory, getTokenSupply, getNetworkStatus, getPeers, getVersion, getLedgerChecksum, getAllCertificates, getAllRepresentativeInfo | Querying the network without an account | | UserClient | All Client methods plus: send, setInfo, generateIdentifier, allBalances, balance, head, chain, history, state, updatePermissions, createSwapRequest, transmit, listACLsByPrincipal, getCertificates, modifyCertificate, sync | Any operation requiring an account | | Builder | Batch operations: send, receive, setInfo, modifyTokenSupply, modifyTokenBalance, computeBlocks, publish | Multi-step operations that should execute atomically | | Account | Static utilities: fromSeed, fromPublicKeyString, generateRandomSeed, generateNetworkAddress, seedFromPassphrase, isIdentifierKeyType + AccountKeyAlgorithm enum | Account creation and key management | | Block | Block construction: Builder, OperationType enum, AdjustMethod enum, NO_PREVIOUS | Low-level block building | | Permissions | Permission construction methods | Access control | | Config | getDefaultConfig | Network configuration |

Anchor SDK (Fully Dynamic)

Anchor services and lib modules are not hardcoded — they are auto-discovered from SDK exports at runtime. When the SDK adds new services, they appear automatically.

Discovery flow:

keeta_list_sdk_methods({ target: "AnchorCatalog" })
  → lists all services and lib modules with their methods

keeta_list_sdk_methods({ target: "AnchorService:FX" })
  → drill into a specific service

keeta_list_sdk_methods({ target: "AnchorLib:Resolver" })
  → drill into a specific lib module

Execution flow:

keeta_anchor_execute({
  subtarget: "service",
  serviceName: "FX",        ← any service name from the catalog
  method: "getQuotes",
  args: [...]
})

keeta_anchor_execute({
  subtarget: "lib",
  libModule: "Resolver",    ← any lib module from the catalog
  method: "getRootMetadata",
  args: []
})

Currently discovered services (as of anchor SDK v0.0.49):

| Service | Methods | Purpose | |---|---|---| | FX | getQuotes, getEstimates, getPrices, listPossibleConversions, etc. | Foreign exchange and token swaps | | KYC | createVerification, getCertificates, getSupportedCountries | Identity verification | | AssetMovement | getProvidersForTransfer, getProviderByID → provider: initiateTransfer, createPersistentForwardingAddress, listTransactions, shareKYCAttributes | Cross-chain/cross-rail transfers | | Username | resolve, resolveMulti, claimUsername, search, signUsernameTransfer | On-chain usernames | | Notification | getProviders, getProvider → provider: registerTarget, createSubscription, listSubscriptions | Push notifications |

Currently discovered lib modules:

| Module | Type | Key Members | |---|---|---| | Resolver | class | getRootMetadata, lookup, listTokens, listTransferableAssets, clearCache, Metadata (static) | | Certificates | namespace | Certificate, CertificateBuilder, SensitiveAttribute, SharableCertificateAttributes | | EncryptedContainer | class | fromPlaintext, fromEncryptedBuffer, grantAccess, revokeAccess, getPlaintext, verifySignature | | URI | namespace | parseKeetaURI, encodeKeetaURI, assertKeetaURIString |

Future services and modules will auto-appear in the catalog without MCP server changes.
