Manifest MCP

MCP servers for Manifest Network and Cosmos SDK chains.

Exposes on-chain queries and transactions as Model Context Protocol tools, so any MCP-compatible client (Claude Desktop, Cursor, etc.) can interact with the blockchain through natural language.

Building a TypeScript app (not an MCP integration)? Use @manifest-network/manifest-sdk — the app-building SDK that composes the chain + Fred behind one typed client. See its README and the SDK cookbook.

Monorepo structure

packages/
  core/        @manifest-network/manifest-mcp-core      Shared library: Cosmos logic, on-chain tool functions, server utilities
  chain/       @manifest-network/manifest-mcp-chain     MCP server for chain operations (6 tools, +1 optional faucet)
  lease/       @manifest-network/manifest-mcp-lease     MCP server for on-chain lease operations (8 tools)
  fred/        @manifest-network/manifest-mcp-fred      MCP server for provider/Fred operations (12 tools)
  cosmwasm/    @manifest-network/manifest-mcp-cosmwasm  MCP server for MFX-to-PWR converter (2 tools)
  agent-core/  @manifest-network/manifest-agent-core    TypeScript orchestration surface (deploy / manage-domain / troubleshoot / close-lease)
  agent/       @manifest-network/manifest-mcp-agent     MCP server wrapping agent-core via MCP elicitation (5 orchestrated tools)
  node/        @manifest-network/manifest-mcp-node      CLI entry points + encrypted keyfile wallet
  sdk/         @manifest-network/manifest-sdk           App-building SDK: aggregates core + fred + agent-core behind one typed surface (for TS apps, not MCP)

Dependency direction: node -> {chain, lease, fred, cosmwasm, agent} -> core (node also depends on core directly); agent -> agent-core -> {core, fred}; sdk -> {core, fred, agent-core} (never reverse).

Prerequisites

• Node.js >= 22.19.0 (declared via engines on every package)

• npm >= 10 (ships with Node 22+)

Quick start

# Install dependencies
npm install

# Build all packages
npm run build

# Generate an encrypted wallet keyfile (interactive)
node packages/node/dist/chain.js keygen

The five CLI binaries (manifest-mcp-chain, …) are bin names shipped by @manifest-network/manifest-mcp-node, not package names. To run one without a clone, name the package and select the bin — npx <bin-name> on its own resolves the bin name as a package and fails:

npx -y -p @manifest-network/manifest-mcp-node manifest-mcp-chain keygen

See packages/node/README.md for wallet setup and MCP client integration.

MCP tools

Chain server (manifest-mcp-chain) -- 6 tools (+1 optional)

Lease server (manifest-mcp-lease) -- 8 tools

Fred server (manifest-mcp-fred) -- 12 tools

The Fred server also exposes 3 MCP resources (manifest://leases/active, manifest://leases/recent, manifest://providers) and 3 prompts (deploy-containerized-app, diagnose-failing-app, shutdown-all-leases).

CosmWasm server (manifest-mcp-cosmwasm) -- 2 tools

Agent server (manifest-mcp-agent) -- 5 orchestrated tools

Wraps @manifest-network/manifest-agent-core orchestration via MCP elicitation — bidirectional plan / confirm / recovery prompts flow over standard MCP wire. The broadcasting tools require an elicitation-capable host (Claude Code ≥ 2.1.76); the read-only tools (lookup_custom_domain_orchestrated, troubleshoot_deployment_orchestrated) run on any host.

Modules reachable via the chain server's cosmos_query / cosmos_tx (enumerate with list_modules): bank, staking, distribution, gov, billing, sku, group, wasm, poa, tokenfactory, ibc-transfer, authz, feegrant, auth (query only), mint (query only), manifest (tx only).

Documentation

Development

For a deeper look at the codebase design, see ARCHITECTURE.md.

# Build all packages
npm run build

# Type-check workspace packages and the E2E suite
npm run lint
npm run lint:e2e

# Run unit tests
npm run test

# Run E2E tests (Linux, local Docker, XFS project quotas; see docs/e2e-setup.md)
npm run check:e2e-env
docker compose -f e2e/docker-compose.yml up -d --wait --wait-timeout 180
npm run test:e2e
docker compose -f e2e/docker-compose.yml down -v --remove-orphans

# Code formatting and import sorting (Biome)
npm run check        # check only
npm run check:fix    # auto-fix

Adding a new module

1. Create a query handler in packages/core/src/queries/<module>.ts implementing routeXxxQuery()

2. Create a transaction handler in packages/core/src/transactions/<module>.ts implementing routeXxxTransaction()

3. Register both in the QUERY_MODULES / TX_MODULES maps in packages/core/src/modules.ts

The module is then automatically available through the cosmos_query and cosmos_tx tools, and discoverable via list_modules and list_module_subcommands.

Releasing

All nine packages are versioned in lockstep and published together.

Setup (one-time)

The release workflow uses npm OIDC trusted publishing (provenance). No npm token is needed as a repository secret -- authentication is handled automatically via GitHub's OIDC identity provider. Ensure the npm package is linked to the repository for provenance to work.

Publishing a release

# 1. Bump versions (updates all package.json files and syncs the lockfile)
npm run release:version -- 0.2.0

# 2. Commit and tag
git add -A
git commit -m "chore: release v0.2.0"
git tag v0.2.0

# 3. Push (triggers the release workflow)
git push origin main --tags

Pushing a vMAJOR.MINOR.PATCH tag triggers the Release workflow, which:

1. Validates the tag version matches all package.json files

2. Builds, type-checks, runs Biome checks, and tests

3. Publishes all packages to npm (with provenance) in dependency order: core → chain → lease → fred → cosmwasm → agent-core → agent → node → sdk (the release workflow is the source of truth for the list and order)

4. Creates a GitHub Release with auto-generated notes (best-effort — publish succeeds even if this fails)
