| Summary | Local proxy that collapses N downstream MCP servers into 4 meta-tools with progressive tool discovery (measured: 122 tools → 4, 28.6K tokens of definitions saved), compresses large tool outputs (HTML→Markdown, JSON structure summarization, base64 stripping — 60–95% measured on real pages/APIs) with full-output retrieval via readmore, and prints a per-session token-savings report. Security-relevant outputs are never silently compressed. Install: npx -y context-firewall --config config.json | Self-hosted source-available MCP gateway and API-to-MCP bridge. Converts REST, SOAP/WSDL, GraphQL, and SQL/NoSQL databases (PostgreSQL, MySQL, MariaDB, MSSQL, Oracle, MongoDB, SQLite) into MCP tools — no SDK, no code. Imports OpenAPI / Postman / WSDL / GraphQL specs; bridges multiple MCP servers behind one endpoint. Ships with 29 pre-built adapters (DHL, DATEV, Weclapp, Personio, Handelsregister, Shopware 6, VIES, OpenPLZ, Bundesbank, etc.). OAuth2 (PKCE + Client Credentials), Bearer, API Key, WS-Security, TLS certs. AES-256-GCM credential encryption, full audit log, per-user MCP API keys, tool-level RBAC. |
