EchoRelay is a multi-tenant HTTP relay: callers hit your versioned API lines, EchoRelay authenticates, rate-limits, and bills the request, then fans it out to your target URLs with retries and a dead-letter queue. The MCP server is the management plane — your agent can set up and operate a project end to end: create lines and endpoints, dry-run endpoint configs, manage API keys and key policies, invite team members, check billing and credits, read request logs and metrics, and retry or discard DLQ entries. Every tool carries read-only/destructive annotations, so MCP hosts can auto-approve reads and confirm destructive actions. Authentication is a Bearer token created in the EchoRelay panel.

When your AI runs git through a shell, it reads back raw command output — hundreds of tokens of noise to extract one piece of information. GitEasy MCP returns structured data: branch names, changed files, commit history — exactly what your AI needs, nothing extra. The same git operation at a fraction of the token cost. 21 tools, plain English, zero shell parsing.

Collective procedural-knowledge network for AI agents — the shared route map of the agent economy. Before attempting a non-trivial task (API integration, multi-step procedure), agents query Waymark for verified routes: step sequences and known gotchas other agents documented. After finishing, they attest the outcome, building trust scores by consensus. 100+ expert routes live across Stripe, GitHub, Slack, Salesforce, Kafka, Postgres and ~50 more domains. Blind-graded benchmark: 3.6× more known failure modes avoided, +45% first-try success (waymark.network/benchmark). Remote streamable-HTTP server — no install: https://mcp.waymark.network/mcp · Live dashboard: mcp.waymark.network/dashboard

MCP Advisor & Installation - Use the right MCP server for your needs

A production MCP server giving AI agents live Polymarket data as native tools: market search and prices, insider-scored whale trades (each verifiable by on-chain tx hash), trader leaderboards across 10 categories and 4 time windows, and wallet P&L profiles. Hosted on Apify (Streamable HTTP, pay-per-call, no API keys); the only hosted zero-install option among Polymarket MCP servers. Fully async, fail-loud data integrity.

AutoSearch exposes a complete systematic-review pipeline as 6 MCP tools — not a thin search wrapper. `autosearch_run_research` launches an async PRISMA 2020 run (multi-source academic search across OpenAlex, Crossref, PubMed, Semantic Scholar, arXiv, ClinicalTrials.gov, DBLP and DOAJ; screening with recorded inclusion/exclusion decisions; evidence synthesis; IMRAD paper with APA references and PRISMA flow counts). Companion tools poll status, fetch the finished paper (markdown/JSON/PDF), verify any DOI live against Crossref, run one-shot evidence searches, and list runs. Citations are verified by construction: every DOI is checked against the Crossref API before it enters a deliverable, and a re-runnable citation-integrity benchmark is published at https://exatoshi.uk/trust (latest: 99/99 DOIs resolved, 0 fabricated, across 23 real deliverables — failures would be published too). Auth is a single `x-api-key` header; free account includes 50 credits. Docs with schemas, JSON examples and credit costs: https://exatoshi.uk/developers
