Deixis
Deixis is a Model Context Protocol (MCP) server that gives coding agents typed access to Language Server Protocol (LSP) operations. It manages explicitly configured language servers for one project and exposes their semantic capabilities without adding another filesystem, shell, editor, index, or memory layer.
[!WARNING]
Deixis is pre-alpha. Its semantic tools and guarded rename workflow work, but
no stability guarantees are available yet.
Capabilities
A configured Deixis session exposes fifteen read-only MCP tools by default. Starting it with --allow-mutation adds apply_rename as a sixteenth tool.
Deixis negotiates UTF-8, UTF-16, and UTF-32 positions, synchronizes documents from disk before file-scoped requests, gates every operation on the language server's advertised capabilities, and preserves source-server provenance in results. Several language servers may serve one immutable project root.
Recoverable LSP cancellations are retried up to three times after a bounded readiness wait. Retries share the original request timeout and stop when the MCP caller cancels. If retries are exhausted, the error reports the attempt count and preserves the language server's error details.
Navigation, hover, signature help, references, symbols, and call-hierarchy preparation also retry empty results observed during indexing and ContentModified errors within the same timeout and three-retry limit. After an empty result, Deixis waits for readiness up to the request deadline instead of spending retries while indexing continues. A server that remains busy produces a request_timeout error (30 seconds by default). ContentModified errors wait up to five seconds for readiness per retry. File-scoped retries verify that both the synchronized document and its contents on disk are unchanged before reusing a position. Nonempty results and empty results from servers with ready or unknown status throughout the request return immediately.
