Palinode MCP Server

Audit-grade memory for AI agents. Every stored claim can carry an explicit epistemic status (fact / inference / open_question / unverified), typed links to the evidence that backs or contradicts it, and a verifiable quote-level citation to its source. MCP-first, so one memory works in every editor. Its 31 documented tools cover session, archive, doctor.

People who work with session, archive and doctor and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Palinode

before you install - you'll need

PALINODE_DIR

Environment variables documented in the project's README - it lists which are required and which have defaults.

Claude Code

claude mcp add phasespace-labs-palinode -- uvx palinode

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "phasespace-labs-palinode": {
      "command": "uvx",
      "args": [
        "palinode"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

pypi package palinode - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.phasespace-labs is GitHub-verified and matches the repo owner

03 · What Palinode can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can browse memory files by type, filter by core status, read the full content of a memory file, fetch a URL and save as research, and archive ephemeral memories whose TTL has expired.

Capability map

Tools grouped from the project's README - what Palinode lets an agent do.

read & search

3 tools - e.g. Hybrid BM25 + vector search with category filter; resolve attaches bounded evidence and a resolution per hit; Browse memory files by type, filter by core status; Read the full content of a memory file

search · list · read

Session

2 tools - e.g. Session-start context digest for the resolved project scope; Capture summary, decisions, and blockers at end of session

session_init · session_end

Archive

2 tools - e.g. Retire one memory that's wrong or obsolete - archive it, or supersede it with a named replacement; Archive ephemeral memories whose TTL has expired

archive · archive_expired

Doctor

2 tools - e.g. Fast diagnostic pass - 18+ checks across paths, services, config, index; Full diagnostic with canary write test (~10–15s)

doctor · doctor_deep

Resolve

1 tool - e.g. What memory holds right now for a question or one record - what stands, what replaced what, conflicts with both sides intact, and what is explicitly unknown

resolve

Save

1 tool - e.g. Store a typed memory (person, decision, insight, project)

save

Ingest

1 tool - e.g. Fetch a URL and save as research

ingest

Entities

1 tool - e.g. Entity graph - cross-references between memories

06 · Palinode FAQ

Is Palinode still maintained?

Yes - as of 2026-09-18, its last commit was 2026-09-17 and it shipped 10+ releases in the last 90 days. We re-verify nightly.

What can Palinode do?

With this server connected, an agent can browse memory files by type, filter by core status, read the full content of a memory file, fetch a URL and save as research, and archive ephemeral memories whose TTL has expired.

How do I install Palinode?

Run `uvx palinode`. The README documents one environment variable (PALINODE_DIR) to set first. You can also paste the ready-made client config above.

Does Palinode run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
