anarco·mcp is a knowledge base service that acts as a curated, provenance-tracked librarian over The Anarchist Library. It is designed to be connected to an AI assistant over the Model Context Protocol (MCP) so that questions about anarchist thought are routed to primary texts from the library. The service returns answers that include citations to verbatim passages and surfaces disagreements between different schools of anarchist thought rather than collapsing them into a single view.
The service operates as a read-only, public endpoint over standard MCP Streamable HTTP, ensuring that answers are traceable to specific passages without fabricating citations. It functions as a librarian for AI assistants, offering a curated, human-mapped index of topics such as property, justice, and organization. The platform positions itself as a specialized knowledge base service that provides structured access to anarchist political thought, sourced from The Anarchist Library.
The system follows four commitments: map-first, not search-first; every claim is traceable; fails loud, never fabricates; and returns the disagreement. A human-curated map sends each question to the exact texts that answer it, while keyword search is a fallback that is allowed to miss. Every claim is traceable back to an original text and a verbatim passage, past the Library, to where the Library itself got the text.
The service covers nine topics including Crime & justice, Police abolition, Property & ownership, Money & markets, Work & coordination, How anarchists organize, and Self-governance. Each topic is a hand-built map of who argues what, spanning the tradition’s real fault lines. First-hand accounts like Ukraine 1918 and Spain 1936 are tiered above theory on questions of practice.
The service explicitly highlights disagreements between different anarchist schools of thought, such as Mutualist, Individualist, Communist, and Egoist views on property. It refuses to flatten five tendencies into one “anarchist view” and presents the argument between them. The tradition splits on property, with Proudhon defining it as robbery, Tucker defending it against state monopoly, and Kropotkin seeing it as might.
The platform is designed for users of MCP-compatible AI clients, including Claude, ChatGPT, and Gemini. It allows them to query texts with verifiable provenance rather than relying on generative AI interpretation. The server returns the map, the files, the search hits, and the cited passages, while your assistant composes the answer.
The service is built on The Anarchist Library, a volunteer archive of anarchist texts. Sources are used under the Library’s open redistribution stance. anarco·mcp serves short cited passages and points readers back to the full works, acting as a librarian, not a mirror.
The service explicitly states that “anarcho-capitalism” is out of scope by design. The corpus follows The Anarchist Library, which is anti-state and anti-capital. This scope ensures that the curated map focuses on specific fault lines within the anarchist tradition.
The service returns errors or “not covered” responses rather than fabricating answers. A citation that can’t resolve returns an error, and it is never invented. Fails loud, never fabricates, and a confident wrong answer is beaten by a clear “not covered by this library” response.

The availability across various clients like Claude and Cursor is reassuring. The public, read-only endpoint ensures easy access, though one should verify plan requirements for specific tools like ChatGPT connectors to ensure smooth integration.
From the information available, the technical setup appears straightforward, yet the value proposition remains somewhat ambiguous for casual users. The service offers a curated, provenance-tracked knowledge base that routes questions to primary texts and returns disagreement between schools of thought. While this is excellent for researchers who need to trace every claim back to a verbatim passage, the distinction between the map-first approach and keyword search might be confusing. The text states it is a public, read-only endpoint, which suggests low barrier to entry, but it is unclear if there are usage limits or if premium features exist beyond the basic connector. For someone considering this company, the lack of explicit pricing or tiered features means one must assume it is free or usage-based without clarity. The emphasis on anti-state and anti-capital scope is clear, but the specific utility for non-experts is not fully detailed. It seems best suited for those already familiar with the Anarchist Library, as the tool acts as a librarian rather than a search box. Without clear metrics on response time or accuracy benchmarks, it is difficult to assess the quality beyond the theoretical promise of failing loud rather than fabricating. Ultimately, while the concept is sound, the absence of transparent pricing or service level agreements leaves some uncertainty about long-term reliability and cost for heavy users who might require extensive querying capabilities.
Connecting via a simple URL with no account required is incredibly convenient for testing different assistants immediately.
What stands out is the refusal to flatten five tendencies into one view. The tool correctly routes questions to primary texts, presenting the argument between schools rather than offering a single answer. The structured approach to topics like property and defense is thorough. It serves as a reliable map for understanding the diverse landscape of anarchist thought without editorial bias.
The provenance tracking is genuinely useful, allowing me to trace claims back to verbatim passages. However, relying on keyword search as a fallback means some queries might miss the curated map entirely. For serious study, it works well, though the retrieval-only model requires more manual synthesis than a full AI agent would provide.
