MCP Servers

Checks whether a project idea already exists before your agent scaffolds it. Searches GitHub, npm and Python repos, drops archived/inactive results, and returns at most 3 maintained alternatives with a concrete "extend this instead" suggestion for each. The calling agent does the relevance judgement itself, so no extra API key is needed. npx -y reuse-before-generate

A semantic search engine for files and code — find files by describing what they do, not their names. Local reusable indexes, configurable embedding providers (OpenAI, Gemini, Voyage, any OpenAI-compatible API, or fully offline local models), AST-aware code chunking, optional reranking. uvx vexor mcp or pip install vexor.

Self-hosted MCP for live docs, code audits, snippets, and best practices across 445+ libraries. 14 tools, 107 audit patterns with file:line precision, BM25-ranked snippets, lockfile-aware version pinning, npm/PyPI/crates.io/Go fallback. No API keys, no rate limits, Context7 alternative. npx -y @groundtruth-mcp/gt-mcp

Check whether an LLM model id is deprecated, retiring, or retired, and what to migrate to. Covers OpenAI, Anthropic, Azure, Bedrock, Google, and Cohere. No API key. npx -y @llmintel/mcp or https://llmintel.ai/v1/mcp

🎖️ - Connector between LLM agents and world data - 1,500+ endpoints aggregating 160+ primary sources across 36 data domains: markets, macroeconomics, company fundamentals, government, news, climate, maritime, and entity screening. Install via pip install sugra-api-mcp or hosted at app.sugra.ai/mcp.

Airflow REST API — 7 tools (DAG list, runs, task instances, log tails, trigger, clear). dag-health-rollup aggregation. Airflow 3.x /api/v2 + JWT (SimpleAuthManager); pin 0.1.x for Airflow 2.x. Read-only by default; trigger/clear write-gated.

Convert unstructured business documents (PDF, DOCX, invoices, contracts, payroll) into structured, LLM-ready datasets with automatic classification, field extraction, PII masking (10+ locales), and quality scoring. 6 async MCP tools covering the full pipeline: submit → poll → extract → build → export JSONL/RAG/CSV. Install: pip install flexorch-mcp.

🎖️ - Read-only-by-default MCP server for Datanika, the open-source ELT + dbt platform: browse connections, preview data, run and compile dbt transforms, monitor runs, and manage pipelines. 25 tools; opt-in --allow-write enables create/trigger.

Search, query, and publish charts across 2,300+ verified public datasets (World Bank, IMF, Eurostat, OECD, WHO). 28 MCP tools for data discovery, analysis, and visualization. Remote MCP + npm package.

Manage Apache Airflow through its REST API — list DAGs, inspect DAG runs and task instances, trigger runs, and check failed-DAG and scheduler/metadatabase health. 7 tools, built with FastMCP. Install: uvx mcp-airflow.

Search and enrich data from 250M+ companies across 50+ countries. Company lookup by name, VAT, or ID, NACE sector search, and financial data from official EU business registries. Free tier: 50 lookups/month. Install: npx scala-mcp-server.

MCP-first operations toolchain for SQLite, Cloudflare D1, and Turso. Inspect, diff, migrate, monitor, back up, and repair databases over stdio. Read-only by default; writes are opt-in, dry-run first, and auto-snapshot before applying. npx -y litescope mcp

Query SQLite, PostgreSQL, and MySQL in plain language — read-only by design, with column hiding/masking, row caps, per-query timeouts, cost-based rejection, and rate limiting.

The MCP server that remembers your database — persists table/column annotations, an FK relationship graph, and searchable notes across sessions, so the model stops re-discovering your schema every time. PostgreSQL, MySQL, MSSQL, SQLite; read-only-enforced.

Connect Redash to Claude — natural-language SQL with safety guards (blocks DROP/TRUNCATE, PII detection), BIRD-based smart table selection, plus saved queries, dashboards, widgets, and alerts.

Query PostgreSQL, MySQL, Redshift and SQL Server over verified SSH / AWS SSM tunnels, with read-only enforcement, confined file exports, and pluggable secret providers (env, Vault, AWS Secrets Manager, RDS IAM). Published on the official MCP Registry.

Inspect and operate Redis-backed job queues (Asynq and BullMQ): per-state counts, job detail with decoded payload and last error, and faithful retry/delete running each library's own scripts. Read-only mode for production.

Natural language to validated SQL engine with multi-connector support (PostgreSQL, MySQL, Snowflake, BigQuery, DuckDB), document QA, semantic caching, and self-hosted MCP server.

One MCP server for PostgreSQL, MySQL, and SQLite. Unified read-only tools (listdatabases, listtables, describetable, runquery) across all three engines with two-layer read-only enforcement (SQL-text guard + DB-level read-only transactions). Install: npx -y mcp-multi-db.

Ground-truth Firestore schema context for AI coding agents. Stops Cursor, Claude, and Windsurf from hallucinating field names and queries. Scans live collections, returns real field names, types, and presence rates.

Django ORM static-analysis MCP server. Nine read-only tools (listapps, listmodels, describemodel, findrelations, cascadepreview, erdiagram, describemigrationdependency, suggestindexes, signalgraph) that expose Django schema, relationships (FK/M2M/O2O, ondelete, relatedname), migration deps, missing indexes, and signal graphs — no DB, no Django boot, no credentials. Companion to a VS Code / VSCodium / Cursor extension (Open VSX verified) and a django-orm-lens PyPI CLI. pip install django-orm-lens

Production-grade PostgreSQL MCP server with 100+ tools for catalog introspection, AST-validated safe query execution, index tuning, natural-language SQL, pgvector/TimescaleDB/AGE integrations, and HTTP/stdio transports.

Local, contract-governed federation across files and databases (Postgres, Snowflake, BigQuery, DuckDB, Excel, and more) with read-only guards, PII masking, and per-column agent access.

Read-only trust layer for Postgres: the agent never writes SQL — twelve tools compile it from definitions you control, PII and secret categories are refused before the query runs, and every call lands in a tamper-evident SHA-256 audit chain.
