## Quality 76/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- n/a `auth.secret_in_url`: no templated URL

### tool hygiene: 64 (weight 30)

- pass `tools.descriptions`: every tool has a description
- warn `tools.description_length`: 1 tools have descriptions over 1,024 characters, which crowds the context
- pass `tools.schemas`: every tool has an object input schema
- fail `tools.annotations`: no tool declares readOnlyHint or destructiveHint, so clients cannot tell safe calls from risky ones
- fail `tools.directory_hints`: no tool declares all four of readOnlyHint, destructiveHint, idempotentHint and openWorldHint; missing: plan_workflow (readOnlyHint, destructiveHint, idempotentHint, openWorldHint); run_workflow (readOnlyHint, destructiveHint, idempotentHint, openWorldHint)
- pass `tools.token_cost`: about 617 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 100 (weight 15)

- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- tools: 2, about 617 tokens to load them all
- tool set hash: 88e7603de9051c76effcfd501ebdd6d1
- badge: [![protogrid quality](https://protogrid.dev/badge/com.agenticpaywall/composer.svg)](https://protogrid.dev/servers/com.agenticpaywall/composer)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (2)

- `plan_workflow`: Ask Composer whether it can do a multi-step data/research task for you, and at
what price. Free — nothing is charged, no payment involved.

Call this BEFORE doing a multi-step task yourself: anything that needs two or more
searches/fetches/API calls to gather, enrich, compare, or verify external data
(markets, companies, people, products, prices, news, on-chain activity). Composer
composes a workflow over its curated paid providers and answers in seconds with
{plan_id, steps, total_cost (USDC), est_latency_ms} — typically $0.02–$0.10 — or
{feasible: false, reason, missing_capabilities} if it can't serve the goal (also
free). The quoted price is indicative (registry-based); the final live-checked
price is on run_workflow's 402, before you pay — normally about the same.

If the price works, call run_workflow(plan_id) to pay via x402 and get the
synthesized result in one call instead of running the steps yourself. A run that
fails after payment is refunded.

Goals are open-ended. Two validated fast paths:
• competitor-pricing — e.g. "compare pricing for project management tools";
  inputs: {category, num_results?}.
• diligence-pack — e.g. "run diligence on Anthropic";
  inputs: {subject, token_address?, chain?, num_results?}.
`agent_id` is optional — identify yourself for attribution if you like.
- `run_workflow`: Run a workflow Composer planned for you and get the synthesized result. PAID
via x402 — one payment replaces the multi-step work you'd otherwise do yourself.

Pass the `plan_id` from plan_workflow. This call is payment-gated: it returns an
x402 402 carrying the final live-checked price (normally ≈ plan_workflow's
indicative quote); your x402 client pays it (settled on Base), and Composer then
executes the multi-step workflow — paying each provider from its own wallet — and
returns the synthesized answer. You pay Composer's price for the outcome
(principal/reseller); the 402 is authoritative, and a run that fails after
payment is refunded.
