YodMCP — Agent Operating System

YodMCP is a production-oriented Agent Operating System kernel on MCP: multi-graph memory, Tasks, Skills, A2A, attestation (software / simulated TEE), OpenTelemetry, and plan-based monetization.

This README is written so a senior engineer with only this file + the source tree can install, deploy every surface, exercise features, and verify end-to-end.

Package surfaces

Surface	Command	Default	Purpose
MCP	yodmcp	stdio	Local MCP clients (Cursor, Claude Desktop, etc.)
MCP HTTP	yodmcp --http --port 8000	:8000/mcp	Remote / Streamable HTTP MCP
API	yodmcp-api --port 8080	:8080	REST health, memory, audit, skills, billing
A2A	yodmcp-a2a --port 9000	:9000	Agent Card, message, tasks
SDK	from yodmcp.sdk import YodClient	HTTP client	Thin client for the API
Skills	skills:// + skills/*/SKILL.md	auto-loaded	Agent Skills as MCP resources
Verify	pytest + scripts/verify_e2e.py	CI	Substrate + durable + TEE modes

Requirements

• Python 3.11 or 3.12 (3.10+ declared; CI covers 3.11/3.12)
• Optional: Docker for multi-service compose

Install

git clone https://github.com/ANAMIZED/YodMCP.git
cd YodMCP
python -m venv .venv && source .venv/bin/activate   # recommended
pip install -e ".[dev]"

Copy environment defaults:

cp .env.example .env

Variable	Default	Meaning
YODMCP_MEMORY_BACKEND	memory	memory | sqlite | durable
YODMCP_MEMORY_DB	./data/yodmcp_memory.db	SQLite path when durable
YODMCP_ATTEST_MODE	software	software | simulated_tee | nitro | sgx
YODMCP_PLAN	free	free | pro | enterprise
YODMCP_TENANT_ID	default	Soft quota tenant key
YODMCP_SKILLS_DIR	(auto)	Override skills root
STRIPE_SECRET_KEY	unset	Enables live Checkout Sessions

TEE honesty: nitro / sgx are provider hooks; without real TEE libraries they fall back to simulated claims. Prefer software or simulated_tee for local verify.

Quick start (local)

# 1) MCP over stdio (attach from an MCP client)
yodmcp

# 2) REST API
yodmcp-api --port 8080
# curl http://127.0.0.1:8080/health

# 3) A2A
yodmcp-a2a --port 9000
# curl http://127.0.0.1:9000/a2a/card

MCP client configuration (stdio)

Cursor — project .cursor/mcp.json or global MCP settings:

{
  "mcpServers": {
    "yodmcp": {
      "command": "yodmcp",
      "args": [],
      "env": {
        "YODMCP_MEMORY_BACKEND": "memory",
        "YODMCP_PLAN": "free",
        "YODMCP_ATTEST_MODE": "software"
      }
    }
  }
}

If yodmcp is not on PATH, use the module form:

{
  "mcpServers": {
    "yodmcp": {
      "command": "python",
      "args": ["-m", "yodmcp"],
      "cwd": "/absolute/path/to/YodMCP",
      "env": {
        "PYTHONPATH": "src",
        "YODMCP_MEMORY_BACKEND": "memory"
      }
    }
  }
}

Claude Desktop — same shape under mcpServers in claude_desktop_config.json.

Streamable HTTP MCP (remote clients that support URL transport):

yodmcp --http --host 0.0.0.0 --port 8000
# endpoint: http://127.0.0.1:8000/mcp

Docker

docker compose up --build
# API  :8080  A2A :9000  MCP HTTP :8000

Single API container:

docker build -t yodmcp .
docker run --rm -p 8080:8080 -e YODMCP_PLAN=free yodmcp

Verify end-to-end (no external accounts required)

# Unit + integration
YODMCP_MEMORY_BACKEND=memory YODMCP_ATTEST_MODE=software \
  PYTHONPATH=src pytest tests/ -v

# Durable SQLite + simulated TEE
YODMCP_MEMORY_BACKEND=sqlite YODMCP_MEMORY_DB=/tmp/yodmcp.db \
  YODMCP_ATTEST_MODE=simulated_tee \
  PYTHONPATH=src pytest tests/ -v

# Exhaustive substrate script
PYTHONPATH=src python scripts/verify_e2e.py

Expected: all tests green; script prints ALL E2E CHECKS PASSED.

API smoke (with yodmcp-api running):

curl -s http://127.0.0.1:8080/health
curl -s http://127.0.0.1:8080/api/skills
curl -s http://127.0.0.1:8080/api/billing/plans
curl -s http://127.0.0.1:8080/api/billing/status

SDK:

python examples/sdk_quickstart.py   # requires API on :8080

MCP tools (catalog)

Tool	Description
memory_write	Persist into multi-graph hierarchical memory
memory_read	Retrieve with embedding similarity
memory_consolidate	Promote high-importance episodic to semantic
memory_stats	Node/edge counts
tasks_create / tasks_get / tasks_cancel / tasks_stats	Durable async task handles
skills_list	List Agent Skills (+ resource URIs)
a2a_card	A2A Agent Card JSON
plan_cache_get / plan_cache_put	Semantic plan cache
cache_stats	Cache statistics
attestation_recent	Recent TRACE-style claims
audit_recent	Recent policy/audit events
discover_capabilities	Progressive discovery of tools + skills
echo	Connectivity probe

Resources:

• skills://{name} — skill markdown body
• yodmcp://agent-card — agent card JSON

Skills

Built-in skills are always registered. Disk skills under skills/*/SKILL.md are loaded automatically (override via YODMCP_SKILLS_DIR). Repo ships:

• memory-hygiene, safe-tool-use, funding-usdc, repo-bootstrap
• Plus built-in long-horizon-planning

Monetization

Plan	$/mo	Tool calls/day	Durable	TEE
Free	0	500	—	—
Pro	49	50k	yes	simulated
Enterprise	499	unlimited	yes	Nitro/SGX hooks

• Soft quotas via tool gate; upgrade messaging on exhaustion
• Live Stripe Checkout when STRIPE_SECRET_KEY is set; otherwise checkout returns status: payment_link

Plan	Link
Pro	https://buy.stripe.com/bJe3cw0kCaLrbVz1AY43S09
Enterprise	https://buy.stripe.com/9B68wQ1oGcTz9NrfrO43S0a

Non-custodial USDC (preferred for agents)

Known limitations (read before claiming production)

1. Plan cache uses lightweight embeddings; default similarity threshold is 0.68 (not production vector search).
2. TEE Nitro/SGX are hooks with simulated fallback unless you wire real providers.
3. Frontend src/yodmcp/frontend/dashboard.py still uses legacy core.runtime and is not the primary control plane — use yodmcp-api + MCP tools.
4. Quotas are soft (in-process meter); not a distributed billing ledger.
5. Processes do not share in-memory state; use sqlite backend + shared volume for multi-process durability.
