Project mention: 300+ languages doesn't mean what you think: three tiers of code understanding | dev.to | 2026-08-08
I am not the first person to look at this. aider evaluated stack-graphs and went with tree-sitter tags plus PageRank instead (#534). So did OpenHands (#742) and SWE-agent (#38). Three serious teams reached the same conclusion: too much work, unmaintained upstream, not worth it.

For databases: crystaldba/postgres-mcp (3.3k stars) has a "Restricted Mode" that "Limits operations to read-only transactions and imposes constraints on resource utilization" and is described as "suitable for production environments". bytebase/dbhub (3.5k stars, release 2026-09-02) covers Postgres, MySQL, SQL Server, MariaDB and SQLite with "Read-only mode, row limiting, and query timeout to prevent runaway operations". Google's MCP Toolbox for Databases (16k stars) ships "Prebuilt generic tools for instant data exploration (e.g., list_tables, execute_sql)". The original reference Postgres server from the Model Context Protocol project is archived; the current reference set is filesystem, git, fetch, memory and a few others.
