RAGfly — MCP Interface
Connect any MCP-compatible LLM agent (Claude Code, Cursor, Cline, etc.) to your RAGfly group's documents and capabilities. The agent discovers tools automatically — no integration code required.
Prerequisite
An API Key for your group. See INTEGRATION.md § Credentials.
Quick setup (remote mode — recommended)
No installation required. Add to your MCP client:
Claude Code — .mcp.json (project) or ~/.mcp.json (global)
SSE (compatible with all clients):
{
"mcpServers": {
"ragfly": {
"url": "https://api.ragfly.ai/mcp/sse",
"headers": {
"Authorization": "Bearer slm_live_xxxxxxxxxx"
}
}
}
}
streamable_http (more efficient, better with HTTP/2 and proxies):
{
"mcpServers": {
"ragfly": {
"url": "https://api.ragfly.ai/mcp-http/",
"headers": {
"Authorization": "Bearer slm_live_xxxxxxxxxx"
}
}
}
}
Restart your client. Tools appear with the prefix mcp__ragfly__.
Cursor / Cline / other MCP clients
Register the SSE URL and the Authorization header. Consult your client's documentation for the exact format — the protocol is standard MCP.
Available tools
| Tool | Description | Parameters |
|---|---|---|
estado_sesion |
Verifies the connection and returns the user context | — |
listar_documentos |
Lists group documents with filters | estado, limite, pagina |
ver_documento |
Full detail of a document | codigo_documento |
listar_espacios |
Lists the group's Workspaces | limite |
ver_espacio |
Workspace detail: criteria + documents + queue | id_espacio, limite_docs |
ver_cola |
Current state of the processing pipeline | proceso, estado, limite |
ver_ejecuciones |
Skill execution history | limite |
listar_habilidades |
Catalog of available LLM skills | — |
ver_habilidad |
Skill detail: prompt, model, output type | codigo_habilidad |
ejecutar_habilidad |
Queues execution over a workspace or document | codigo_habilidad, id_espacio?, codigo_documento? |
buscar_chunks |
Direct semantic search over the corpus | q, limite |
preguntar |
Natural language question with full RAG (stream) | texto, id_conversacion? |
Always call estado_sesion first to confirm the connection is valid.
Document estado values
CARGADO · METADATA · ESCANEADO · CHUNKEADO · VECTORIZADO · NO_ESCANEABLE · REVISAR
Queue estado values
PENDIENTE · EJECUTANDO · COMPLETADO · ERROR
Example flow (agent)
# 1. Verify connection
estado_sesion()
→ {"usuario": "bot-finance", "grupo": "COMPANY", "rol": "DOC-ADMIN"}
# 2. Ask over documents
preguntar(texto="What are the penalty clauses in the 2024 contracts?")
→ RAG response with chunk citations
# 3. List vectorized documents
listar_documentos(estado="VECTORIZADO", limite=10)
# 4. Execute a skill over a workspace
ejecutar_habilidad(codigo_habilidad="RESUMIR_DOCUMENTO", id_espacio=42)
# 5. Monitor progress
ver_cola(estado="EJECUTANDO")
Local stdio mode (alternative)
If you already have the RAGfly client installed and need to operate on the local filesystem:
pip install ragfly
ragfly login
Config in .claude/settings.json:
{
"mcpServers": {
"ragfly-local": {
"command": "ragfly-mcp",
"args": []
}
}
}
The local mode exposes the same tools but reads the JWT from ~/.ragfly/credentials.json. Useful when the agent also needs to scan local directories with ragfly local escanear.
Permissions
Each tool operates in the context of the API Key's user — same RBAC as the web interface. An agent with role DOCS-USUARIO-FINAL can read but cannot execute skills.
Troubleshooting
| Error | Cause | Solution |
|---|---|---|
HTTP 401 before handshake |
Invalid or revoked API Key | Check the key at app.ragfly.ai/api-keys |
| Tools don't appear | Client not restarted | Restart the MCP client |
estado_sesion returns error |
Expired JWT (local mode) | ragfly login |
HTTP 403 on a tool |
Role lacks permission for that operation | Ask the admin for a role with more permissions |
Codex
Codex supports MCP via codex mcp add. Use the streamable_http endpoint:
codex mcp add ragfly \
--url https://api.ragfly.ai/mcp-http/ \
--bearer-token-env-var RAGFLY_API_KEY
See QUICKSTART.md for the full walkthrough with setup, test script, and case table.
Practical differences
| Feature | Codex | Claude Code / Cursor |
|---|---|---|
| Setup | codex mcp add with --bearer-token-env-var |
.mcp.json with URL + header |
| Tools | mcp__ragfly__estado_sesion() etc. |
mcp__ragfly__estado_sesion() etc. |
| Authentication | --bearer-token-env-var RAGFLY_API_KEY |
Declared in .mcp.json |
| Discovery | MCP protocol automatic | MCP protocol automatic |
