Paleobiology MCP Server - install, status & alternatives [2026]

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"
    }

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

license Apache-2.0 - declared in the repository

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 run a read-only SQL SELECT over occurrence sets staged on a DataCanvas by paleobiology_search_occurrences. SELECT only, and list the tables and columns staged on a DataCanvas. Call before paleobiology_dataframe_query to discover table and column names.

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. The flagship; b
paleobiology_get_taxon: - Resolve a taxon by name or taxon_no to its accepted name, rank, classification, parent, occurrence count, and first/last-appearance (FAD/LAD) range. Run first t
paleobiology_get_diversity: - Compute a diversity / origination / extinction curve for a clade across geologic time, binned by period, epoch, or age. Returns the full bin set inline.
paleobiology_list_intervals: - Look up the geologic time scale - eons through ages with absolute-age (Ma) boundaries and nesting. Translates named intervals ↔ Ma. Served offline from a bundle
paleobiology_search_collections: - Find fossil collections (localities) by area and geologic time, with their formation, lithology, depositional environment, and co-occurring-fossils count. Paged
paleobiology_dataframe_query: - Run a read-only SQL SELECT over occurrence sets staged on a DataCanvas by paleobiology_search_occurrences. SELECT only.
paleobiology_dataframe_describe: - List the tables and columns staged on a DataCanvas. Call before paleobiology_dataframe_query to discover table and column names.
paleobiology_dataframe_drop: - Drop a single staged table to free memory before its TTL expires. Opt-in - registered only when PALEOBIOLOGY_DATAFRAME_DROP_ENABLED=true.
