Matthias Meyer - StudioMeyer

Cache Kit

studiomeyer-io

Leak-safe caching for the Model Context Protocol's SEP-2549 cache hints (ttlMs + cacheScope) — set them right server-side, and never serve a private result across users/tenants client-side.

Otel

studiomeyer-io

W3C Trace Context bridge for the Model Context Protocol — propagate traces through MCP _meta (SEP-414) and emit OpenTelemetry spans so Host → MCP server → tool → downstream shows up as one trace.

Spec Migrator 2511

studiomeyer-io

MCP Spec 2025-11-25 migration toolkit: detect, diff, compatibility-matrix, plan, check. Foundation pillar by StudioMeyer (MCP Factory).

Stateless Migrator

studiomeyer-io

MCP Spec 2025-11-25 -> 2026-07-28 RC migrator: scan + diff + patch + verify CLI. 8 detection rules. AST-rewrite via ts-morph. Foundation pillar by StudioMeyer (MCP Factory).

Stdio Shellguard

studiomeyer-io

Defense-in-depth bundle for MCP stdio servers: drop-in guardExec/guardSpawn wrappers, AST audit CLI, reference MCP server. Closes the Ox-Security 200k-server stdio-RCE class (LiteLLM CVE-2025-69256). MIT, TypeScript, Node >= 20.

Rce Guard

studiomeyer-io

Foundation Pillar 9: Layer-3 RCE defense for MCP servers via policy synthesis + behavioral CVE replay + cross-server canary tracking. v0.1 descriptor-only; v0.2 ships native enforcement.

Tenant Context

studiomeyer-io

AsyncLocalStorage tenant + actor context propagation for MCP servers. Zero runtime dependencies, ESM-only, TypeScript.

Tenant Pair

studiomeyer-io

Foundation library + reference MCP server for multi-user tenancy (couples, families, groups). Bi-temporal storage, conflict-resolver interface, SQLite + Postgres adapters, MCP-Spec 2025-06-18.

Hook Conformance

studiomeyer-io

Test-harness CLI that audits any MCP server for Claude Code v2.1.118 mcp_tool lifecycle-hook readiness — idempotency, latency, determinism, side-effects, GDPR-doc. 56/56 tests, MIT, Foundation Build #3 of the StudioMeyer MCP Factory pillar set.

Server Attestation

studiomeyer-io

Layer-2 supply-chain hardening for MCP servers — Ed25519-signed tool manifests, runtime spawn-attestation, default-deny argument sanitizer. Defends against marketplace-poisoning + CVE-2025-69256 + CVE-2025-61591.

Protocol Conformance

studiomeyer-io

Conformance test harness for Model Context Protocol servers — JSON-RPC 2.0, OAuth 2.1 PKCE, tool schemas, capabilities, smoke roundtrip, annotation hygiene. Spec versions 2024-11-05, 2025-03-26, 2025-06-18.

Passport

studiomeyer-io

Publish-readiness validator for the MCP Registry. Checks server.json (schema, reverse-DNS name, packages, transport) + cross-checks version/mcpName with package.json/Cargo.toml/pyproject.toml before mcp-publisher. Single Rust binary, SARIF, GitHub Action.

Covenant

studiomeyer-io

Contract & breaking-change detector for MCP servers — semver for your interface. Snapshot tools/resources/prompts into a lockfile, diff in CI, fail on breaking changes. Single Rust binary, SARIF, GitHub Action.

Gauntlet

studiomeyer-io

Reliability + security testing for Model Context Protocol servers — mcp-fuzz (schema-aware fuzzer, SARIF) and mcp-storm (load tester, p50/p95/p99, CI gating) on one fast async MCP client core.

Armor

studiomeyer-io

Drop-in Rust sidecar for MCP servers — scans tool calls for prompt injection, validates Ed25519 manifest signatures, blocks marketplace-poisoning vectors. <5ms p99 overhead. Defense against OX Security MCP advisory (10+ CVEs, April 2026).
