Fleet: Contract-Truth sweep — the advertised contract lies about the runtime (proven on gtex + panelapp)

The defect class

An MCP server's advertised contract — its JSON Schema, tool descriptions, capabilities payload, MCP resources, server-instructions string, and README/docs — is what an LLM reads to decide how to call it. When that contract claims something the runtime does not honour, the agent obeys the contract and fails. The cost is silent and recurring: burned round trips, wrong provenance, or a capability the agent believes exists and never gets.

Two bugs in this class were fix

Fleet conformance: gate the three recurring behavioural bugs (silent-empty filter, lying total, non-actionable error) — 74 confirmed instances

Summary

Complements #68, which asked for a sweep of the remaining 19 backends and predicted they would not be clean. They are not: a live audit of all 21 backends produced 74 independently-confirmed defects (each reproduced twice — once by a tester, once by a verifier instructed to refute it). Results are reported into #68; this issue proposes the gate that would stop them recurring.

The distinction from #68: that issue is about the advertised contract **lying about the runtim

Standard: TOOL-SURFACE-BUDGET-STANDARD v1 — cap the tool-surface token cost (pubtator is 37% of a 200k context)

Summary

The fleet has no budget for the one cost every client pays on every session, before any work happens: the tools/list payload. Measured against the live fleet, that cost is now large enough to change model behaviour, and two servers alone would blow a client's context budget.

This proposes a TOOL-SURFACE-BUDGET-STANDARD v1, in the same house style as MCP-TRANSPORT-STANDARD-v1 / RESPONSE-ENVELOPE-STANDARD-v1.1, with a CI gate.

Measured today (live, public endpoints)

outputSchema is ~54% of the fleet's tool surface — the response models are too big to publish (see correction below)

Summary

~54 % of the fleet's entire tool surface is outputSchema. The cause is a FastMCP default, not fleet code — which is why it appears nowhere in any of our repos and has gone unnoticed. One fix repairs all 22 servers.

Root cause (verified against the installed FastMCP, not inferred)

fastmcp/server/server.py:309      FastMCP(..., dereference_schemas: bool = True)   # <-- default TRUE

### security: re-pin current UniProt MCP definitions in the release baseline (R-02 regression)

## Severity
Medium

## Problem

The router release-candidate artifacts are internally consistent but no longer represent current fleet source. `ci/release-candidate-inventory.json:24-27` pins UniProt at `157b17ea7f328d0fdb4c514d805a6c69668c4a3d`; current `uniprot-link` main is `9e9330a8136e`.

Current UniProt deliberately changes `search_sparql_query`: it permits bounded SELECT/ASK only, rejects `SERVICE`/CONSTRUCT/DESCRIBE, removes graph result formats, and emits output schema plus explicit ann

### bug: discoverability is confusing

The tools were always there. My mistake was in how I searched.
The genefoundry MCP is a meta-router. The real annotation tools (spliceai_predict_splicing, vep_annotate_variant, etc.) sit behind genefoundry's own search_tools/call_tool interface. They are not registered as individual top-level tools that my client-side tool_search indexes.
The first time, I used tool_search (the client tool-discovery function) with queries like "spliceai splice prediction." That only ever surfaces the four direct

### oauth: advertised issuer has a trailing slash — RFC 8414 well-known derivation 404s

## Summary

The router advertises its OAuth issuer with a **trailing slash**. RFC 8414 §3 derives the
metadata URL by inserting `/.well-known/oauth-authorization-server` between the issuer's
host and its path component — applied naively to an issuer that already ends in `/`, that
produces a doubled slash, and the resulting URL **404s**.

This is the same bare-origin/trailing-slash family as the 2026-08-07 ChatGPT connector
outage (`f"{base_url}/token"` → `https://genefoundry.org//token`, fixed i

### feat: add provider-compatible strict schema and compact tool-selection views

## Problem

The canonical direct GeneFoundry MCP tool surface works for Gemma 4 and Claude-class models, but two provider compatibility gaps block fair direct-tool evaluation for current OpenAI and Gemini models.

1. OpenAI strict structured-output requests reject tool schemas with optional properties or open object shapes before tool execution.
2. Gemini degrades with the roughly 30-tool catalog: bounded runs repeat tool discovery and can exhaust their turn budget before returning a final answe

### OAuthProxy resource check and the PRM derive the resource URI differently (root cause behind the v0.6.8 tolerance patch)

Tracking the proper fix so the `_install_resource_tolerance()` workaround restored in #81 / v0.6.8 can eventually be removed.

## The underlying FastMCP inconsistency
For a server mounted at `/mcp` via `server.http_app(path="/mcp")` inside FastAPI, two derivations of the RFC 8707/9728 resource URI disagree:

- **OAuthProxy resource check** (`proxy.py` `authorize`) uses `self._resource_url`, which under the live mount equals `resource_base_url` **verbatim** — `set_mcp_path` receives the sub-app's

### MCP Registry publish has failed on every tag since v0.6.6 (mcp-publisher arch 404)

## Symptom
The **MCP Registry** workflow (`mcp-registry.yml`, runs on every `v*` tag) fails at *Install mcp-publisher*:

curl: (22) The requested URL returned error: 404 https://github.com/modelcontextprotocol/registry/releases/latest/download/mcp-publisher_linux_x86_64.tar.gz gzip: stdin: unexpected end of file


Confirmed failing identically on **v0.6.6, v0.6.7, v0.6.8** — so the router's entry in the official MCP Registry has not been refreshed since v0.6.5. Directories poll that entry

### security: nothing asserts GF_PUBLIC_BASE_URL + GF_MCP_PATH == GF_JWT_AUDIENCE — a typo makes the router mint tokens it then rejects

## Summary

The router derives its OAuth resource identity from `GF_PUBLIC_BASE_URL` + `GF_MCP_PATH`, and validates incoming tokens against `GF_JWT_AUDIENCE`. Nothing asserts that these agree:

GF_PUBLIC_BASE_URL + GF_MCP_PATH == GF_JWT_AUDIENCE


If they diverge, the router advertises one resource identifier in its RFC 9728 metadata (so clients obtain tokens with *that* audience) while validating against a different one — it effectively **mints tokens it then rejects**, with a 401 that

### Replace HEAD-based fleet validation with manifest-to-runtime provenance

## Problem

Issue #51 exposed an incorrect release assumption: a deployed backend should **not** be compared with the current GitHub default-branch HEAD. Source and production intentionally move at different rates, so that comparison makes a healthy, intentionally pinned deployment appear invalid.

The router needs to verify the released fleet actually running in an environment, not whatever has most recently merged upstream.

## Goal

Introduce an immutable, reviewed **fleet release manifest**

### security(fleet): digest-pin + image scan + SBOM parity across all -link backends

**Surfaced risk (Low, supply chain).** The **router** already digest-pins its base image (`docker/Dockerfile` `python:3.14-slim@sha256:…`) and runs image scanning + drift in CI (`.github/workflows/container-security.yml`, `drift.yml`). Most `-link` backends do **not** yet.

**Fix:** adopt the router / `pubtator-link` CI as the fleet template — digest-pin base images, add Trivy/Grype scan (fail on HIGH/CRITICAL), generate an SBOM — per `CONTAINER-HARDENING-STANDARD-v1`.

### security(pubtator-link): harden optional write/`full` profile surface

**Surfaced (read-only exception).** The fleet is read-only by default; `pubtator-link` is the one exception. Its `full` profile exposes state-mutating tools (Postgres writes), an **arbitrary-file-create** in `export_review_audit_bundle` (path not jailed), and **unbounded list inputs** (`index_review_evidence`). The hosted default `lean`/`readonly` profile + read-only rootfs already blunt this.

### security(autopvs1-link): third-country transfer + PII logging + result authenticity

**Surfaced risk (Med).** `autopvs1-link` screen-scrapes a third-party service `autopvs1.bgi.com` (CN) with a spoofed browser User-Agent, forwards possibly patient-derived variants to it, and logs client IP + full query path at INFO.

For an EU hospital this is simultaneously:
- a **third-country transfer** (GDPR Ch. V) of potentially Art. 9 data,
- **PII-in-logs**, and
- an **authenticity** risk — the "classification" is parsed from an external page that can change, break, or be poisoned.

**Fix

### security: fleet-wide untrusted-content fencing envelope for returned text (indirect prompt injection)

**Surfaced risk (MCP-specific, Med):** returned literature/free-text is the primary indirect-prompt-injection surface (OWASP LLM01, tool-poisoning / lethal-trifecta). The router is a thin aggregator and passes backend text to the model unchanged — verified: no fencing in `genefoundry_router/`.

**Current state (verified 2026-07-10):**

- Partial output sanitizing in t
