Bay Run

Bay Run

Bay Run is the decision and execution layer for durable specialist Pins at the canonical origin: https://run.huggingbay.xyz.

The default MCP front door is exactly three tools, in this order: coprocessor, run_pin, solve_task.

Quickstart: connect to MCP

Use the canonical Streamable HTTP MCP endpoint: https://run.huggingbay.xyz/mcp/. The live copy-paste auth and request contract is kept at https://run.huggingbay.xyz/quickstart.

Mint a resource-bound demo bearer, then make the primary Guard-first call:

BASE=https://run.huggingbay.xyz
TOKEN=$(curl -fsS -X POST "$BASE/oauth/token" \
  -H 'Content-Type: application/json' \
  -d '{"grant_type":"urn:bay-run:grant-type:demo","scope":"mcp:demo","resource":"https://run.huggingbay.xyz/mcp/"}' \
  | python3 -c 'import json,sys; print(json.load(sys.stdin)["access_token"])')

curl -fsS -X POST "$BASE/mcp/" \
  -H "Authorization: Bearer $TOKEN" \
  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"coprocessor","arguments":{"user_text":"<untrusted request>"}}}'

coprocessor runs the canonical Guard first and never generates text or executes tools. Add documents when retrieved chunks need bounded post-SAFE reranking. Read its action and evidence before deciding whether a caller-owned generation or tool call may continue.

Default MCP tools

Point an MCP client at https://run.huggingbay.xyz/mcp/. The public default surface is:

• coprocessor — the primary bounded Guard-first call over user_text and optional documents.
• run_pin — the direct alias for one of the four canonical Pins, using its published {pin_id,input} shape.
• solve_task — the open-ended fallback when no canonical Pin matches; provide task_description and input.

Advanced compatibility capabilities remain available through explicit live references:

• OpenAPI
• advanced MCP tools
• full LLM reference
• SDK and framework integrations

Trust and data policy

Read the canonical data policy before sending input. The live quickstart documents receipt semantics, 401 recovery, and the published limits; do not infer capabilities from advanced routes.

Hugging Bay mirror catalog

Hugging Bay’s mirror catalog is available at https://huggingbay.xyz. Use each artifact's published download plan for the currently admitted files. A drop-in HF_ENDPOINT compatibility origin is not part of the public contract yet, so this repository does not advertise one prematurely.

For current catalog and serving information, use the generated Bay Run status snapshot. Mirror counts and family breakdowns are intentionally not copied here because they change.
