Suggested fixes

  1. Consider ONE guarded general-query tool exposing the backend's native query language (see snapshot-free graphql_query) so long-tail intents need no new endpoints.
Fix it with Claude Code

Paste this into Claude Code inside the MCP’s repo — it carries the failing checks, the fix list, and the conventions the router grades against.

You are upgrading the MCP service "Otto AI" so an AI router can reliably discover, choose, and call its tools. Pantessa's Reason Router just graded it 95/100 (A). I'll point you at the service's codebase; audit it against the findings below and implement the fixes.

## Failing checks
affordances (80%):
  - no escape-hatch tool — every uncovered filter needs a new endpoint (whack-a-mole)

## Fixes, in priority order
1. Consider ONE guarded general-query tool exposing the backend's native query language (see snapshot-free graphql_query) so long-tail intents need no new endpoints.

## The conventions to build to (what the router needs)
- **Param schemas on every tool/endpoint**: name, type, required-vs-optional, and a description per param. A router refuses to construct calls it cannot validate — schema-less endpoints are invisible.
- **Descriptions that carry user intent**: write what a USER would ask ('crypto spot price by symbol — price of ETH, BTC…'), never what the URL is. Include 2–3 example queries.
- **One guarded escape hatch instead of endless params**: if the backend has a native query language (GraphQL/SQL), expose ONE read-only general-query tool with strict guardrails (single read-only operation, allowlisted root fields, depth + page-size caps, response truncation) and a compact schema card in the tool description (root fields + useful filters + one example). Long-tail intents then need no new endpoints.
- **Declare user-identity params**: any param that should be the CALLER's own address (their votes, follows, balances, orders) must say so in its description ('the user's own wallet address') so routers can inject identity server-side instead of guessing.
- **Server-side joins for the headline intent**: if answering the #1 user question takes two chained calls (e.g. resolve follows → filter proposals), add one param that does the join server-side.
- **Build, don't execute**: anything signable returns an UNSIGNED payload (typed data / tx template) for the user's own wallet. Never hold keys, never sign, never submit on the user's behalf.
- **Free tiers still need rate limiting**: no payment gate means no natural throttle.

Start by reading the tool/endpoint definitions and their input schemas, then apply the fixes smallest-first. After each change, restate which failing check it clears.

Audit before you build: if a fix describes a capability the service ALREADY provides (e.g. an escape hatch or identity param that exists but the grader missed), do NOT duplicate it — say so, skip it, and note it back as a likely router-side scoring gap on Pantessa rather than an MCP deficiency. Only change what this service actually controls.

    at volume≈ $7.20/day @ 1 call/min·≈ $432/day @ 1 call/sec

    Schedule 13D and 13G activist stake filings by ticker: every beneficial-ownership filing made about a US-listed issuer in the last 365 days, each validated against its own cover page so a company's outbound filings about OTHER companies are excluded. Returns 13D vs 13G counts, amendments, reporting-person names and EDGAR links. 13D is the schedule filed without a passive/qualified certification. Public-domain SEC EDGAR. $0.005 per call.

    8-K filings by ticker — the item-coded SEC material-event feed: every 8-K a US-listed company filed in 90 days, tagged with the SEC's own item codes and official titles (1.01 material agreement, 1.05 cybersecurity incident, 3.01 delisting notice, 5.02 officer change, 8.01 other). Returns event and filing dates separately, amendments labelled, EDGAR links. Earnings-only filings excluded and counted. Public-domain SEC EDGAR. $0.003 per call.

  • GET/analyst-ratings$0.003
    x402.ottoai.services

    Analyst consensus for a vendor-resolved equity: the latest buy/hold/sell distribution (strong buy · buy · hold · sell · strong sell counts, total, and a deterministic consensus label) plus up to six months of the same distribution so an agent can read the DRIFT — is the street moving toward or away from the name. Vendor counts (Finnhub), our label rule stated in the payload. No price targets and no per-analyst grade actions are served.

    at volume≈ $1.44/day @ 1 call/min·≈ $86.40/day @ 1 call/sec

    Base-chain ecosystem news for Base-native agents, not the general crypto firehose. Up to 12 Base-scoped headlines from the last 48h, each with its own permalink and publication timestamp, screened against the general /crypto-news feed; `screen` states what was dropped. The AI topic read is optional and is withheld, never padded with macro, when there is no Base coverage. Refreshed hourly from cache; a read past the freshness window pulls inline.

    x402.ottoai.services

    at volume≈ $2.88/day @ 1 call/min·≈ $173/day @ 1 call/sec

    Base social intelligence: a Base sentiment read + quality-screened Base tokens (CoinGecko-listed, market-cap/age/liquidity gated) catching attention, each labelled with the basis it stands on (`rankedBy`: measured trusted-KOL signal, or the on-chain screen plus engagement), with KOL quotes inside a published window (`evidenceWindowDays`). Served from a cached snapshot while fresh (≤1h) and regenerated on demand when a read finds it stale.

  • POST/bridge$0.01
    x402.ottoai.services

    at volume≈ $14.40/day @ 1 call/min·≈ $864/day @ 1 call/sec

    Base chain status from Otto's own RPC: the four heads an agent needs before it acts — latest (~2s soft), safe, L1-finalized and the pending Flashblocks preconfirmation head — with base fee (wei+gwei), congestion, block age and the finality lag between them. Makes the Base pending-vs-latest gap explicit. Flat JSON, refreshed every minute, honest staleness meta. Base chain status, block height, base fee, finality, chain health. $0.001 per call.

    Agent-native earnings facts: when a company reports, get the numbers that move the stock — total & segment revenue, EPS and gross margin (GAAP and non-GAAP, always labeled), next-quarter guidance — each with its source line. Figures go live from the wire within minutes of the release; the SEC 8-K exhibit version supersedes them, and every response names its source document. Refuses honestly until the release is out; never advice.

    Latest company news for a vendor-resolved equity: licensed Finnhub headlines from the trailing seven days with publication time, source, and summary.
