Gridstamp MCP server

Read from the package source without running it. The installed server may list more.

• distance_between

  Calculate distance in km between two GPS coordinates using the Haversine formula.

• list_settlements

  List all spatial settlements for this robot.

• list_stamps

  List all spatial stamps for this robot, most recent first.

• proof_chain

  Generate a proof chain showing the robot's path between locations. Useful for delivery verification and audit trails.

• robot_status

  Get robot status: ID, total stamps, memories, settlements, last known location.

• spatial_memory_recall

  Recall spatial memories near a location or matching tags.

• spatial_memory_store

  Store spatial context to persistent memory. Tags a location with metadata for later recall.

• spatial_settlewrite action

  Create a spatial settlement — payment that requires proof-of-presence at a location. Used for delivery confirmation, service completion, and location-based contracts.

• spoof_checkwrite action

  Run anti-spoofing analysis on a stamp. Checks for GPS spoofing signals: impossible speed, duplicate timestamps, coordinate anomalies.

• stamp_locationwrite action

  Create a tamper-evident spatial stamp at a GPS coordinate. Returns a cryptographically signed proof-of-presence receipt.

• verify_proof_chain

  Verify an entire proof chain for continuity and integrity. Checks each stamp and validates the sequence.

• verify_stamp

  Verify a spatial stamp's integrity. Checks HMAC signature and timestamp to detect tampering.
