Paleobiology MCP Server

@cyanheads/paleobiology-mcp-server Search fossil occurrences, resolve taxon fossil ranges, plot diversity through deep time, and look up the geologic time scale via MCP. STDIO or Streamable HTTP. Its 8 documented tools cover paleobiology, dataframe.

People who work with paleobiology and dataframe and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Paleobiology MCP Server

before you install - you'll need

Set MCP_TRANSPORT_TYPE, MCP_LOG_LEVEL before connecting.

Claude Code

claude mcp add cyanheads-paleobiology-mcp-server --transport http https://paleobiology.caseyjhand.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "cyanheads-paleobiology-mcp-server": {
      "url": "https://paleobiology.caseyjhand.com/mcp"
    }
  }
}

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

Using another client? Same JSON, different key

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 · remote - your agent's requests go to paleobiology.caseyjhand.com

endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

npm package @cyanheads/paleobiology-mcp-server - published under the repo owner's npm scope (@cyanheads)

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

03 · What Paleobiology MCP Server 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 resolve a taxon by name or taxon_no to its accepted name, rank, classification, and FAD/LAD range - the name-resolution gateway, find fossil collections (localities) by area, geologic time, formation, and lithology, run a read-only SQL SELECT over occurrence sets staged on a DataCanvas, and list the tables and columns staged on a DataCanvas.

The 8 tools it gives your agent

Extracted from the project's README - what paleobiology-mcp-server lets an agent do.

paleobiology_search_occurrences
- Search fossil occurrences by taxon, geologic time, geography, and depositional environment. Every row carries both modern and paleo coordinates; broad results s
paleobiology_get_taxon
- Resolve a taxon by name or taxon_no to its accepted name, rank, classification, and FAD/LAD range - the name-resolution gateway.
paleobiology_get_diversity
- Compute a diversity / origination / extinction curve for a clade across geologic time.
paleobiology_list_intervals
- Look up the geologic time scale - named intervals ↔ absolute Ma boundaries.
paleobiology_search_collections
- Find fossil collections (localities) by area, geologic time, formation, and lithology.
paleobiology_dataframe_query
- Run a read-only SQL SELECT over occurrence sets staged on a DataCanvas.
paleobiology_dataframe_describe
- List the tables and columns staged on a DataCanvas.
paleobiology_dataframe_drop
- Drop a single staged table to free memory before its TTL expires. Opt-in.
