What is mcp-server CLAUDE.md?

A set of Claude Code instructions for working with the Agent Web Protocol (AWP), a standard for describing web-based AI agents. It covers the related server, tools, installation, and important files.

Use it to understand the AWP project, install its MCP server, validate or generate agent.json files, view examples, and follow the implementation guide.

It gives Claude Code the background needed to use AWP without repeatedly looking up its specification or setup details.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00402	$0.00402
Opus 5.5	$0.00161	$0.00161
Sonnet 5.5	$0.00080	$0.00080
Haiku 4.5	$0.00040	$0.00040

Security

Grade A, and why

mcp-server CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

AWP MCP Server

MCP server that gives Claude Code (and any MCP-compatible AI tool) native access to the AWP specification, validator, and generator. Published on npm as awp-mcp-server.

Ecosystem

Repo	Role
spec	Source of truth — the specification
agentwebprotocol.org	Standards website
agent-json.org	Schema reference and validator site
agent.json	npm CLI (`npx agent-json init`)
mcp-server (this repo)	MCP server for Claude Code

GitHub org: github.com/agentwebprotocol

Installation (for users)

Add to ~/.claude/mcp.json:

{
  "mcpServers": {
    "awp": {
      "command": "npx",
      "args": ["awp-mcp-server"]
    }
  }
}

Tools Provided

Tool	Description
`awp_get_spec`	Returns the full AWP specification
`awp_validate`	Validates agent.json content
`awp_generate`	Generates agent.json from parameters
`awp_examples`	Returns 3 example agent.json files
`awp_quickstart`	Step-by-step implementation guide

Key Files

src/index.js — MCP server with embedded spec and all 5 tools

Design Decisions

Spec is embedded in the source (works offline, no network dependency)
Single file server — keeps it simple

Publishing

npm version patch  # bump version
npm publish        # publish to npm

npm account: bshyong158. Auth token in 1Password (Clawdbot vault, "Npmjs" item).

When Spec Changes

Update the embedded spec string in src/index.js, bump version, and publish.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
