Steledger Gateway MCP Server

Steledger — identity & memory for AI agents (steledger-gateway)

A runnable Docker stack: an Emercoin node plus an agent gateway that turns the chain's Name-Value Storage (NVS) into an on-chain identity & memory layer for AI agents. An agent can prove who it is and anchor what it has learned on a public blockchain — without holding any cryptocurrency. Hosted at api.steledger.com; exposed to agents as the steledger MCP server.

🤖 Building with an AI agent? Read AGENTS.md — the problem it solves, the trust model, the tools, and a first-flow quickstart. A ready-to-use Claude Code skill ships at .claude/skills/emercoin-identity/ (invoke with /emercoin-identity). Design notes: docs/ARCHITECTURE.md.

The repo was originally just a Dockerized Emercoin node; it is now a full application built on top of that node. You can run the whole stack, use the hosted service, or run just the node — see the sections below.

What's in here

 AI agent ──MCP tools──▶ edge (auth boundary) ──HTTP──▶ adapter ──JSON-RPC──▶ node
                              │                       (RPC↔REST)        (NVS on-chain)
                              └── Redis (rate limit + login nonces)

Use it as an agent (hosted)

The steledger MCP server is live — no self-hosting needed:

• Streamable HTTP: https://api.steledger.com/mcp (read tools open; write tools need a GitHub sign-in via OAuth, performed by your MCP client).
• Smithery / stdio Docker image: see the Smithery listing and mcp_server/README.md.

Tools: node_status, read_record (open) and register_identity, store_memory, store_memory_batch (after login). Full reference + first-flow in AGENTS.md.

Run the full stack (self-host)

Node (mainnet) + adapter + edge + redis, dev profile:

git clone https://github.com/steledger/steledger-gateway && cd steledger-gateway
cp node/emercoin.conf.example node/emercoin.conf      # set rpcpassword
docker compose -f deploy/docker-compose.yaml --profile dev up -d --build

Edge API on :8000; the adapter's RPC↔REST docs are browsable at http://localhost:8001/docs (dev profile). Wire the MCP server into your agent and run the first flow — see the AGENTS.md quickstart. (Use --profile prod to gate the adapter behind a shared X-Internal-Key.)

Run just the Emercoin node

The node alone (no agent tools) is the default stack — no profile needed. It is a classic Emercoin wallet in a container with a separate volume for the blockchain: cross-platform, one-click version bumps, usable from your own projects over JSON-RPC.

cp node/emercoin.conf.example node/emercoin.conf
docker compose -f deploy/docker-compose.yaml up -d --build

Initial sync takes a few hours, but the RPC is usable right away. By default port 6662 connects to the container:

• address: 127.0.0.1 · user: emcrpc · password: emcpass
• method: POST, e.g. body {"method": "getinfo"}

Change the RPC password:

docker compose -f deploy/docker-compose.yaml exec emc bash changepass.sh
docker compose -f deploy/docker-compose.yaml restart emc

Health check — POST to http://emcrpc:emcpass@127.0.0.1:6662 with {"method":"getinfo"}:

curl --location --request POST 'emcrpc:emcpass@127.0.0.1:6662' \
  --header 'Content-Type: application/json' \
  --data-raw '{"method": "getinfo"}'

A healthy node replies with JSON (fullversion, version, balance, …).

Manage the build:

docker compose -f deploy/docker-compose.yaml stop emc    # stop
docker compose -f deploy/docker-compose.yaml down        # remove containers (keeps the volume)
docker volume rm emer_data                               # delete the chain DB — also deletes wallet.dat!

Status

MVP, verified end-to-end on mainnet: identity registration, signature login, single

• atomic batch memory writes, reads, history, names-by-address. Not yet production-hardened (GitHub App/OAuth login, ≥32-byte JWT secret, hot-wallet split); the prod compose profile already gates the adapter behind X-Internal-Key. Details in AGENTS.md and docs/ARCHITECTURE.md.
