Field-by-field comparison

Compare the evidence before choosing an MCP.

Each signal stays separate, missing facts remain visible, and the column order follows your selection.

MCPs in this comparison

Uncheck an MCP to remove it. Comparing two or three keeps each signal in its own row.

Task fit
Best for
  • Reading and searching PDFs with structured text and tables
  • OCR or rendered PDF evidence with page and bounding-box citations
  • Repository indexing, symbol search, call-path tracing, impact analysis, and architecture queries across many languages
Not ideal for
  • Editing, creating, signing, or rewriting PDF files, which are outside the documented three-tool surface
  • Word, Excel, CSV, or general document workflows outside PDF
  • Tiny repositories, one-off text searches, or semantic questions unsupported by the indexed parsers
Avoid when
  • The process can read sensitive PDF directories that have not been explicitly allowlisted
  • You cannot review the Node and platform-native package chain before installation
  • The source tree cannot be indexed locally or persistent cache files are prohibited

Client coverage noteLocal stdio runs on your computer. Streamable HTTP connects to a remotely hosted MCP server.
Access and data
AuthenticationDefault stdio needs no service credential. Optional HTTP mode supports MCP_API_KEY and binds loopback by default; configured HTTP or OpenAI-compatible visual providers may use their own headers or API key, while local command providers do not inherently require one.No authentication or API key is documented for local stdio. CBM_ALLOWED_ROOT is an optional filesystem containment control; no containment is imposed when it is unset.
CostThe MIT-licensed local server has no documented usage fee. Pricing for any operator-selected external OCR, visual, network, or client provider is outside the Citra documentation and remains provider-specific.The MIT-licensed native software lists no service fee. Local storage and package-manager costs are separate.
PermissionsThe tools read PDF paths and URLs available to the process. Directory allowlists can restrict local reach; URL handling blocks private addresses by default unless the operator overrides it.Indexes repositories, queries code and graphs, performs architecture and impact analysis, manages ADRs and watchers, deletes projects, and writes agent configuration, instruction, Skill, and hook files.
Data handlingDefault stdio processing is local. Optional OCR or visual providers may receive rendered content according to their configuration, and URL inputs are fetched from their source.The publisher says processing is local and code does not leave the machine. Indexes, embeddings, memories, SQLite data, and logs persist under the local CBM cache directory.
Limitations
Tradeoffs
  • Local-first PDF processing reduces routine cloud exposure, but optional OCR and visual providers introduce separate dependencies and data paths.
  • The focused three-tool surface is easier to reason about than a general file server, but it deliberately does not cover document editing.
  • Persistent indexing can reduce repeated reads, but consumes local storage and graph results can become stale until the repository is re-indexed.
Risk contextUse stdio, configure explicit allowed PDF directories, retain private-IP URL blocking, require an API key before any non-loopback HTTP deployment, and review native artifacts before installation.Indexing can capture sensitive files, while persistent graph data and installer/configuration writes expand local exposure. Set CBM_ALLOWED_ROOT, protect the cache, and use explicit project paths.
