Looking for an alternative to Hird? Whether you need a different runtime environment, custom authentication support, or alternative API integrations in the Developer Tools ecosystem, we have cataloged and compared the top alternative MCP servers below.
Compiler-as-MCP-server for the Hirð language (typed actors and effect rows on the BEAM): type inference, definition lookup, effect-row explanation, IR fragments, actor protocol and supervision graphs, and token-budget-aware symbol summaries, so agents query the compiler instead of reading source. Errors come back structured, so an agent can self-correct from tool output alone. cargo install --git https://github.com/no-materials/hird hird-mcp
