"Context7 - Tool or Service Lookup" matching MCP servers:

Real public/bank/school holiday lookup for 206 countries via a rule-based calendar engine (moveable holidays like Easter computed astronomically, not guessed). Priced per call via x402/USDC on Base.

Real-time hydrological information retrieval service that provides water level, precipitation, dam discharge data, and observatory location information.

Enables matching influencers to their talent agencies and agencies to their public creator rosters through an Apify actor.

Graph-based tool retrieval for LLM agents. Builds a tool graph from OpenAPI/MCP specs and retrieves multi-step workflows via hybrid search (BM25 + graph traversal + embedding), recovering accuracy from 12% to 82% with 79% fewer tokens. Also works as an MCP Proxy to aggregate multiple servers behind 3 meta-tools.

Protects AI agents from bad tool outputs, schema mismatches, and tool poisoning by validating, sanitizing, and scoring reliability of tool responses.

Provides agents with real Linux VMs to run commands, manage files, expose ports, and track costs, all through an ephemeral sandbox service.

Tells your agent whether a number is safe to call or text right now. Live US/Canada phone data: carrier, line type, LRN, CNAM, spam/scam reputation, SMS deliverability, and TCPA 8am–9pm calling-window verdicts, plus bulk jobs. Every query is a fresh network dip, never stale cache. Free sandbox key, no card required. Pay per lookup, no minimums.

MCP server that detects and guards against tool poisoning and prompt injection attacks in tool descriptions and schemas. It provides risk scoring, pattern detection, safe rewriting, and audit reports with zero external API cost.

Cross-chain cryptocurrency swaps via Chainflip. Get quotes, execute swaps, and track progress. No API key required to get started.

Analyzes multi-step AI agent tool chains to compute success probability, identify bottlenecks, and suggest better execution orders, enabling more reliable agents via local pure-math computation.
