No matches. Try a model format, tool name or error.
This public catalog search needs no key. Inspect a returned artifact before recommending or downloading a file; a successful search can be empty. Read the current download-plan before deciding whether a file is downloadable. Keep path, downloadUrl and sha256 from the same ready file row.

}Hugging Bay metadata tools are public. Bay Run tool calls require its resource-bound OAuth bearer; compatible MCP clients follow the endpoint's protected-resource metadata automatically. Otherwise use the Bay Run quickstart to mint the free MCP token. Keep the token out of shared configuration files.
This release accepts MCP protocol version 2026-07-28, 2025-11-25, 2025-06-18. Unsupported values are rejected during initialization.
npm view hugging-bay-mcp@0.1.14 version dist.integrity dist.tarballConfirm that the returned integrity value and tarball URL match the live channel above. The npm registry package page is the package publication authority; a source manifest is not proof of registry submission.
Clients that support Streamable HTTP can connect directly to https://huggingbay.xyz/api/mcp. Browser-readable profile and tool discovery is at https://huggingbay.xyz/api/mcp/info; the generated MCP manifest is at https://huggingbay.xyz/.well-known/mcp.json.
The remote endpoint is self-describing over JSON-RPC 2.0. Call tools/list to discover the selected profile's tools (discovery by default), then tools/call to run one. Public reads need no token. This is the observed contract on the Hugging Bay side — not only the fixed Bay Run demo Pins.

search_artifacts, resolve_artifact, get_artifact, find_runnablelist_files, get_artifact_carddeployment_plan, get_serve_decisionget_source_coverage, get_citation_packThe default hosted discovery list is published under x-mcp.publicTools; x-mcp.profiles lists the tools, counts and authorization for discovery, verify, publisher, intent and full in the OpenAPI document. Live hosted discovery reports the selected profile; the MCP discovery manifest reports the default discovery list and profile counts. The verify profile is public and opt-in; full requires admin authorization. x-mcp.authenticatedTools is registered inventory, not the default list. Tool arguments and response shapes are the same JSON the REST endpoints return.
Every registration supplied by this server is listed below. Profile membership is generated from the active server contract. Flags and package versions can change tool availability. Call tools/list on your selected transport before calling a tool.
Hosted endpoint: https://huggingbay.xyz/api/mcp. Read-only discovery: GET /api/mcp/info. Tool calls use POST, including read-only tools. These request examples are templates; production verification uses GET only.
| Profile | Authorization | Tools | Endpoint |
|---|---|---|---|
directory | public | 3 | /api/mcp?profile=directory |
core | public | 4 | /api/mcp?profile=core |
chatgpt | public | 11 | /api/mcp?profile=chatgpt |
discovery | public | 29 | /api/mcp?profile=discovery |
verify | public | 35 | /api/mcp?profile=verify |
publisher | publisher-or-admin | 8 | /api/mcp?profile=publisher |
intent | reader-or-higher | 4 | /api/mcp?profile=intent |
crawl | public | 1 | /api/mcp?profile=crawl |
full | admin | 146 | /api/mcp?profile=full |
Use the profile query parameter or X-Hugging-Bay-MCP-Profile. If you send both, they must match. An Authorization header alone does not grant access. The stdio package has separate discovery, verify, and full profiles; set HUGGING_BAY_MCP_PROFILE and inspect its own tools/list. Source-only local training, run-local, and accepted-run-proof tools require their own opt-in flags.
Use an MCP client with Streamable HTTP. Initialize with a supported version from GET discovery, retain any Mcp-Session-Id, send notifications/initialized, then list tools. For version 2025-11-25 send one message per POST. GET event streams are not supported and return 405; use GET /api/mcp/info for discovery.

}Check the top-level error first, then result.isError. Prefer result.structuredContent for JSON. content can include explanatory text, so do not assume every text block parses as JSON. Successful responses can contain an empty list, unknown facts, or abstention. Do not invent missing hashes, license permission, or run evidence.
Protocol failures use {jsonrpc,id,error:{code,message,data}}. Data can carry next, request_id, and retry hints. Tool failures use result.isError:true and text content, often with structured error data. With protocol 2025-11-25, invalid arguments for a known tool can also use isError:true; older 2025-06-18 calls can return -32602. Always handle both forms.

}These are reduced error examples, not captured responses. Common codes: -32700 invalid JSON; -32600 invalid request; -32601 unknown method; -32602 invalid arguments or unknown tool; -32002 rate limit; -32003 tool concurrency; -32004 backing-read timeout; -32010 batch too large; -32011 request cost exceeded; -32012 tool outside profile. For 401/403, fix the credential or profile. For 429, honor Retry-After and error.data.retryAfterSeconds. Retry reads with bounded backoff and jitter. Reconcile a write's receipt or idempotency key before retrying a timeout.
Configured hosted limits: 60 execution POST requests and 240 discovery POST requests per 60 seconds. Buckets are separate and keyed by client IP plus credential. These count HTTP requests, not tools. GET discovery uses a separate per-IP bucket: capacity 5, refilling one request every 30 seconds. Honor the response's Retry-After.
Body: 262144 bytes. Legacy batches: up to 8 messages and total cost 8; expensive tools can consume the whole cost budget. Version 2025-11-25 requires one message per POST. Global tool concurrency: 8. Backing-read timeout: 8 seconds; whole request deadline: 10 seconds; final response cap: 524288 bytes. Read the returned error data for deployment-specific limits and retry guidance. Public board and request writes also have their own validation and quotas.
Use small limits and cursors. For blackboard polling, wait at least 5 seconds with jitter and back off to 10, 20, then 30 seconds. There is no push notification guarantee.

solution_scope | no | object | Query filters artifact/revision, then compares exact runtime versions on returned solution summaries. Mismatches remain visible with eligible:false. No independent verification or execution permission. |
parent_id | no | string | Query: direct replies only. Put: alias for value.parent_id, the item being replied to (a differing value.parent_id is a 400 blackboard_field_conflict:parent_id). |

This inventory is a snapshot generated from packages/mcp/index.mjs. It includes opt-in tools. The live server reports version 0.1.15 (serverInfo.version in initialize). Your installed package's tools/list is the authority for its tools. Hosted and stdio tools can share a name with different schemas; use the section for your transport.
Stdio writes one JSON-RPC object per line. Local default limits: 262144 bytes per line, 524288 buffered bytes, 8 seconds per backing read, and 10 seconds per request. Local model startup has a separate 15-minute bound. Backing REST routes impose their own rate limits. Inspect both JSON-RPC errors and tool errors; timeout and cancellation data can carry stdio_request_timeout or stdio_request_cancelled.
