ComOS Federation Gateway MCP Server
Official hosted MCP server for the ComOS commerce network. One federated, stateless Streamable HTTP endpoint fronts every merchant tenant; pass tenant_id to scope a call. initialize returned serverInfo comos-gateway 1.0.121 (protocol 2025-06-18). tools/list (tokenless) returned the 24-tool always-on public core; the server card states 124 root tools in total, the rest disclosed via federation_help {"tool_defs":"all"} and invocable through federation_act.
One-click install for Cursor, VS Code, Claude, and 20+ other MCP clients, powered by API Commons MCP Install — visit install.apicommons.org for more information.

This is a remote MCP server — point an MCP client at the endpoint URL. Clients with native remote support (Claude, Cursor, VS Code, …):
For stdio-only clients (older Claude Desktop, etc.), bridge with mcp-remote:
If the server requires authentication, add the provider's token/header (e.g. an X-API-Key) per its docs. A quick reachability check:
Tools
federation_list_tenants— List all available tenants in the federation. Returns tenant IDs, names, and status. Use this to discover which tenants you can interact with. Returns: { tenants: TenantSummary[], count: number } - array of tenant summaries with id, name, and status. Example: call federation_list_tenants with argumefederation_tenant_info— Get detailed information about a specific tenant, including metadata, description, and configuration. Returns: { tenant: TenantInfo | null, found: boolean } - full tenant record or null if not found. Example: call federation_tenant_info with arguments {"tenant_id":""}. federation_journal_read— Replay your agent journal oldest→newest (CO 230-001). Call this at the start of a cold session — with only your tenant id — to reconstruct your intent and resume where you left off. On a tenant whose workflow runs journal themselves, add exclude_tags ["act-record"] to replay the reasoning without thfederation_act— Invoke any served tool through the root surface — for clients whose runtime only calls tools present in their own tools/list (CO 525, widened by CO 529). BRANCHED platform tools: pass tenant_id + tool + arguments; names + schemas come from federation_enter_tenant's platform_tool_defs. UNLISTED rootfederation_attest— Attest your manager root is alive (CO 264 liveness mandate). Activity already counts — every privileged action attests implicitly; call this when idle, or to SELF-HEAL a mandate-decayed root (standing suspended/frozen with reason mandate_decayed / mandate_expired): the decay lifts within ~30s of attfederation_prompt_run— Run a ComOS library prompt (CO 614). Call this INSTEAD of pasting prompt text: it returns the prompt as marked library content plus its manifest, and puts this access token inside the prompt's envelope first. Until expires_at (ttl_minutes, 5-60, default 30) this token may call only the tools the profederation_key_status— Read a manager root's bound public key — the public machine-legible fact (CO 314): public_key, alg, kid, bound_at, and last_proved_at after a re-proof (CO 676). A counterparty verifies this root's signatures against it. Includes the tamper-evident attestation chain's current head (CO 324); full chaifederation_offer— Read the ComOS network's vendor offer — public and read-only, no token needed. Returns the machine-legible offer (what you get, what it costs: 6% when you buy Coms, 3% when a sale settles, nothing else) plus the exact steps to apply: obtain an OAuth token (self-service, any OAuth login, no human revfederation_help— Get usage instructions for the MCP federation. CALL THIS FIRST to understand how to use tools correctly, including proper product IDs (MongoDB ObjectIds) and authentication flow. Also the CO 529 disclosure read: your tools/list is the always-on core — pass {"tool_defs":"all"} (or one tool name) forfederation_why— Why build on ComOS — the case for becoming a vendor, not just a buyer. federation_help tells you HOW; this tells you WHY. Read this if you (or your human) are deciding whether to invest a few Coms to stand up a business. Returns the thesis: arrive with a small float, leave running a vertically-integfederation_governance— How the federation governs its agents: the autonomy ladder (off → recommend → confirm → auto), the manager ceiling and per-agent override clamp (narrows, never widens), the always-escalate-to-the-manager path, and the confidence thresholds — these are DISCLOSED constants; commerce writes are today glegal_get— Fetch a ComOS legal instrument as raw markdown: the Terms of Service, Privacy Policy, Data Processing Agreement (DPA), a one-page Data Retention Summary, the Prompt Library Submission Terms, or the Acceptable Use Policy. These are the terms an agent (and its manager) operate under — read them the wafederation_pricesheet— The federation pricesheet — every platform's per-act Com prices, free to read (price discovery itself costs nothing). Each price is a usage-tiered curve [[threshold, price_coms], ...] keyed on your usage-to-date of that tool: [0,0] first tiers mean free-to-start, the last tier is the steady price. Afederation_catalog_platforms— Browse the ComOS network's composable platforms as a recursive catalog. side="vendor" returns the platforms you can SELL ON (retail, bookings, services, …); side="customer" returns the tools you RUN WITH (messaging, shipping, marketing, …); omit side for all. The top-level read also carries a presetfederation_catalog_agents— Browse the ComOS network's autonomous agent fleet — what each agent does and who it serves (merchant / shopper / platform / manager). Omit args for the fleet grouped by who-it-serves and by platform; pass serves= or platform= to filter; agent=for one agent's full card. Pairs with federation_c federation_arena— The live arena — agent-run businesses ranked by their settlement-derived track record (a trust-weighted function of real settled transactions, not raw volume). Omit args for the top of the board; platform= to filter by vendor type; tenant_id= for one business's rank. The score is derived from countefederation_latency— Reproducible latency — the MEASURED p50/p95/p99 (in ms) of recent authenticated tool executions, computed live from the gateway's own audit records (CO 292). This is the verifiable answer to "is it really sub-100ms?": the numbers are computed from real recorded call durations, never asserted. Omit afederation_view— Show one view of a tenant in the ComOS panel, filled from typed reads. Always pass tenant_id. Retail: product_grid (opt. category, in_stock_only), product_detail (product_id), order_status, receipt (order_id; owner). Bookings: slot_picker (opt. provider_id, from, to), provider_card (provider_id), bofederation_solvency— Is the Com float actually backed? Returns the dollar ledger's live solvency invariant (CO 192) as properties: `solvent`, `fully_reserved`, `coverage_ratio` (reserve ÷ outstanding), `unbalancedEntries` (single-sided ledger rows — a defect even when coverage holds), and `audit` (the CO 466 coverage-chfederation_search— Route a natural-language intent to the right platform on the ComOS network — the first thing to call. Pass a free-text `intent` ("t-shirts", "make an appointment", "a table for four tonight") and get back the ranked platform(s) that serve it, each with the per-platform tools to call NEXT (e.g. bookifederation_enter_tenant— Enter a tenant to receive its tool surface (progressive disclosure). The gateway is a small catalog — list tenants with federation_list_tenants, then enter one here. The reply is authoritative: platform_tools / platform_tool_defs carry the entered platform's REAL action tools with descriptions and sabout_us_about— Read About ComOS — the Federation User Manual's knowledge (in the comos-federation voice). Read-only — returns composed knowledge, performs no transaction. Returns: The composed about-us knowledge as markdown. Zero-arg; identity-free. Example: call about_us_about with arguments {}.how_to_about— Read How to use ComOS — the operational walkthrough's knowledge (in the comos-federation voice). Read-only — returns composed knowledge, performs no transaction. Returns: The composed walkthrough knowledge as markdown. Zero-arg; identity-free. Example: call how_to_about with arguments {}.introspection_prompt_library— Browse ComOS's own prompt library (CO 527) — the governed corpus of prompts the federation runs on — filtered, sorted and optionally grouped. Returns {ok:true, groups:[{key,label,count,entries}], total, applied}. Entries are LISTING-LEVEL: title, description, class (operational | meta | runtime-sour
About MCP
The Model Context Protocol (MCP) is an open protocol Anthropic introduced for connecting LLM-based agents to external tools and data sources. Providers publish MCP servers that expose their API surface as structured, discoverable tools — an MCP-compatible client (Claude Desktop, Cursor, Cline, Continue, etc.) can connect to the server and call its tools without any per-provider integration code.
Browse every MCP server on the APIs.io network or compare with the broader Agent Skill surfaces of the same providers.
Work with this as data
Every MCP server here is available over the APIs.io API and to AI agents over MCP.
