What it does

Fastllm MCP is an agent skill from azrtydxb/Fastllm-proxy. Manage and use MCP servers behind FastLLM — register, patch, delete and list MCP servers on the control plane, and list or call their tools through the gateway. Use when putting one address in front of several MCP servers, granting a client access to a tool, or debugging an MCP tool call.

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering MCP servers. It works with Model Context Protocol. The repository describes itself as: The lowest-overhead LLM router. Production-ready, highly available, one OpenAI-compatible endpoint in front of 80 providers and your own vLLM/SGLang — 0.76 µs per request, no I/O… The licence is Apache-2.0.

When your agent uses it

  • Putting one address in front of several MCP servers
  • Granting a client access to a tool
  • Debugging an MCP tool call

Example prompts

  • “/fastllm-mcp”

What it can do on your machine

Read from SKILL.md and the folder at commit 59a47cf. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Fastllm MCP loads about 515 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 165 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~515

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Auth

Admin endpoints need a session cookie, not a bearer token — the gateway master key is not an admin credential.

bash
curl -sk -c /tmp/ck -X POST https://192.168.10.129:4001/login \
  -H 'content-type: application/json' -d '{"name":"<user>","password":"<pw>"}'
curl -sk -b /tmp/ck https://192.168.10.129:4001/admin/...
<!-- BEGIN GENERATED: endpoints -->
MethodPathSummaryBody fields
GET/admin/mcp-serversList MCP servers. Reports whether a credential is set, never what it is—
POST/admin/mcp-serversRegister an MCP servername, url, transport, description, auth_header, auth_scheme, upstream_api_key, enabled
PATCH/admin/mcp-servers/{id}Update an MCP server. An absent upstream_api_key leaves the stored credential alone; "" clears itname, url, description, enabled, upstream_api_key*
DELETE/admin/mcp-servers/{id}Delete an MCP server—
GET/v1/mcp/serversMCP servers this key may invoke—
POST/v1/mcp/tools/callInvoke one namespaced tool. {"name": "<server>__<tool>", "arguments": {}}—
POST/v1/mcp/tools/listEvery tool across every server this key may invoke, namespaced <server>__<tool>. unreachable names servers that did not answer, so a missing tool is diagnosable—

* optional field

<!-- END GENERATED: endpoints -->

Traps

Two surfaces, two credentials. /admin/mcp-servers needs the admin session cookie; /v1/mcp/* needs a principal API key.

Tool listing goes through the gateway, not the control plane — /v1/mcp/tools/list reflects what the calling principal is allowed to see.
