Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

all
list_all_endpoints
List available Fiber API endpoints with optional tag/search filtering.
call
call_operation
Execute any Fiber API operation by operationId. IMPORTANT: - Most operations require `apiKey` in the request body. - Prefer search_endpoints() first when operation choice is ambiguous. - Use get_endpoint_details_full(operationId='...') first for complex/nested parameter shapes. Args: operationId: The operation ID to call params: Parameters dict: {"body": {...}, "path": {...}, "query": {...}} Returns: API response data or error details.
endpoint
get_endpoint_details_full
Get COMPLETE schema and details for a specific API operation. Use this BEFORE calling an API to understand exactly what parameters are needed. Args: operationId: The operation ID (e.g., "syncContactEnrichment") Returns: Complete schema including all required/optional fields, request body schema, response schema, and example usage.
endpoints
search_endpoints
Canonical API selection tool for endpoint discovery and ranking. Use this first to get the top recommended operations for a user intent. Supports optional constraints plus tag-scoped selection via preferredTags, excludedTags, or a curated tagPack key.
tag
list_tag_packs
List curated tag packs for large tool catalogs. Use this to narrow exploration (for example social-media or enrichment).

Fiber AI — questions

Answers built from our own checks of this server.

What can Fiber AI do?
It exposes 5 tools, read directly from the server on our last check. Among them: call_operation, get_endpoint_details_full, list_all_endpoints, list_tag_packs, search_endpoints. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Fiber AI working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 182 checks got a reply (50.0%), average response time 455 ms. The bar chart above shows every period we have measured.
How do I connect Fiber AI?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Fiber AI need an API key?
No. Fiber AI completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Fiber AI?
It answers our handshake in 455 ms on average, which is faster than 27% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Fiber AI open source?
Yes — it is published under the MIT licence, 0 stars on GitHub and 1 open issue. The source link is on this page, so you can read exactly what it does with your data before you connect it.
