# FieldRobin developer resources

FieldRobin provides a versioned REST API, a public OpenAPI document, an OAuth-protected Streamable HTTP MCP server, and machine-readable AI discovery documents.

## REST API

- [Public OpenAPI 3.1 document](https://fieldrobin.com/openapi.json)
- [Signup and onboarding guide](https://fieldrobin.com/signup.md)
- [Signup flow manifest](https://fieldrobin.com/.well-known/signup.json)
- [API versioning and deprecation policy](https://fieldrobin.com/api-versioning.md)
- Base URL: https://fieldrobin.com/api/v1
- Errors use a JSON envelope with code, message, resolution, and status fields.
- Rate limits use RateLimit-Limit, RateLimit-Remaining, RateLimit-Reset, and RateLimit-Policy. A 429 response includes Retry-After.
- Write-like agent handoffs accept an optional Idempotency-Key header (maximum 128 characters) so clients can retry safely.

## MCP

- [MCP server card](https://fieldrobin.com/.well-known/mcp/server-card.json)
- [MCP server card alias](https://fieldrobin.com/.well-known/mcp.json)
- Streamable HTTP endpoint: https://fieldrobin.com/api/v1/mcp
- 42 authenticated, read-only workspace tools with `readOnlyHint`, `destructiveHint: false`, and `openWorldHint: false` annotations.
- New OAuth registrations receive `mcp:read`; existing clients may continue using legacy `mcp:use`.
- [Protected resource metadata](https://fieldrobin.com/.well-known/oauth-protected-resource)
- [Authorization server metadata](https://fieldrobin.com/.well-known/oauth-authorization-server)
- [OAuth and MCP authentication guide](https://fieldrobin.com/auth.md)
- [Webhook integration guide](https://fieldrobin.com/webhooks.md)

### Quick starts

- Claude custom connector: add the Streamable HTTP endpoint above and complete OAuth; existing Claude users can use the prefilled [FieldRobin connector link](https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=FieldRobin&connectorUrl=https%3A%2F%2Ffieldrobin.com%2Fapi%2Fv1%2Fmcp).
- Claude Code: `claude mcp add --transport http fieldrobin https://fieldrobin.com/api/v1/mcp`, then authenticate from `/mcp`.
- Gemini CLI: `gemini mcp add --scope user --transport http fieldrobin https://fieldrobin.com/api/v1/mcp`, then run `/mcp auth fieldrobin`.
- ChatGPT and Codex: add the endpoint as a remote Streamable HTTP MCP server; OAuth discovery supplies the authorization and registration URLs.

## Agent discovery

- [AI Catalog](https://fieldrobin.com/.well-known/ai-catalog.json) — ARD manifest of the public API, A2A agent, MCP server, and public discovery skill.
- [A2A Agent Card](https://fieldrobin.com/.well-known/agent-card.json)
- [Agent Skills index](https://fieldrobin.com/.well-known/agent-skills/index.json)
- [Public discovery skill](https://fieldrobin.com/agent-skills/fieldrobin-public-discovery/SKILL.md)
- [Scoped developer resources index](https://fieldrobin.com/developers/llms.txt)
- [Scoped API resources index](https://fieldrobin.com/api/llms.txt)
