At a glance
Fetches live Model Context Protocol specification and docs from modelcontextprotocol.io whenever work touches MCP behavior, SEPs or conformance.
- Works in 3 steps: Fetch the documentation index → Identify the relevant page URL(s) from… → Fetch the specific page
- Implementing an MCP feature such as sampling, elicitation or transports
- SKILL.md covers When to use, How to fetch documentation and Presenting information
- Reaches modelcontextprotocol.io
What it does
The skill treats the spec as faster-moving than training data, so it consults live docs for message schemas, required fields, capability negotiation, error handling and transport requirements. It runs proactively when implementing or reviewing MCP features or fixing conformance test failures, and on demand for questions about a feature, spec ambiguities or SEPs, the specification enhancement proposals.
Fetching tries the search_model_context_protocol tool first for ranked results, and otherwise reads the llms.txt index with WebFetch and then the specific pages in the specification, SEP, learning and development sections. It uses the latest spec version unless you ask for a dated version or the draft, answers field-level questions from one page where possible, and cites the source pages it used. It is skipped for pure Kotlin, build or refactoring work with no MCP dependency.
When your agent uses it
- Implementing an MCP feature such as sampling, elicitation or transports
- Fixing MCP conformance test failures
- Looking up what an SEP requires or why a design was chosen
- Checking authorization or capability negotiation rules in the spec
Example prompts
- “What does the spec require for Streamable HTTP reconnection?”
- “Check the live spec for how elicitation requests must be structured.”
- “Why is our conformance test for capability negotiation failing?”
Requirements
- Network access to modelcontextprotocol.io
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Fetch the documentation index
- Identify the relevant page URL(s) from the index. Key sections
- Fetch the specific page
What it can do on your machine
Read from SKILL.md and the folder at commit 32e6483. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
modelcontextprotocol.io
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
MCP Spec Docs Lookup loads about 879 tokens when it runs. Until then it costs about 154 tokens; SKILL.md has 326 words of instructions outside code blocks.
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 326 words (~879 tokens).
“Provides access to the official MCP specification and docs from modelcontextprotocol.io. The spec evolves faster than training data — always consult live documentation for protocol specifics like message schemas, required fields, capability negotiation, error handling, and transport requirements.”
