Codeindex vs Candor

A side-by-side look at the Codeindex and Candor MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.

Verdict: choose Codeindex for biology & bioinformatics work as a local process; choose Candor for biology & bioinformatics as a local process. You can also run both side by side in one mcpServers block.

Tools & capabilities

Codeindex tools 16

  • statusIndex stats: file count, symbol count, indexing state, token savings %, the indexed `workspace` and whether a `watcher` is live
  • searchTrigram-accelerated full-text search across all indexed files
  • find_symbolFind symbol definitions (functions, structs, classes…) by name
  • find_wordExact word/identifier lookup in the inverted word index
  • find_callersCall sites of a symbol, each with the function that holds it. Matched by name, so a same-named definition elsewhere is included
  • get_outlineStructural outline of a file (symbols, line counts)
  • get_treeDirectory tree with file metadata
  • get_importsWhat files does a given file import/depend on
  • get_imported_byReverse dependencies — who imports this file
  • get_change_impactTransitive blast radius: what breaks if a file changes
  • plan_changeFull refactor plan for a symbol or file — definitions, callers, file role, literals, blast radius
  • get_hot_filesRecently changed files sorted by recency

Ready-to-paste client configs

Paste either block (or both) into your client config, e.g. claude_desktop_config.json or ~/.cursor/mcp.json. We only show a config when the install command is confirmed.

Frequently asked questions

Codeindex is categorized under Biology & Bioinformatics and uses a local stdio subprocess. Candor belongs to Biology & Bioinformatics and uses a local stdio subprocess. Pick Codeindex for biology & bioinformatics work and Candor for biology & bioinformatics.

Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.

Codeindex has no declared pricing — check the project's own site. Candor has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.

Yes. MCP clients support multiple servers: add codeindex and candor as separate keys in the same mcpServers object, and your assistant will call tools from either one.

On AllMCPs, Codeindex has a quality signal of 59/100 (Good) with 5 views, 0 installs and 3 GitHub stars. Candor has 45/100 (Fair) with 2 views, 0 installs and 1 GitHub stars.
