Over the last week it answered 50.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

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 502 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 in the form 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 502 ms on average, which is faster than 24% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Fiber AI open source?

The code is open source: it is published under the MIT licence, 0 stars on GitHub and 2 open issues. The licence covers the code in the repository, not the hosted service at mcp.fiber.ai, which runs on its operator's own terms.
