Perception tools (8, 1 write)

write = sends, deletes, buys or posts
  • gns_get_compliance_reportFree

    Returns a full EU AI Act compliance report for a GNS agent, including trust score, chain verification, Merkle epoch proofs, delegation certificate, and regulatory status.

  • gns_get_trust_scoreFree

    Get the current TierGate trust tier and score for an agent. Tiers: provisioned (0%) → observed (25%) → trusted (60%) → certified (85%) → sovereign (99%). Omit agent_pk to query the server's own agent.

  • gns_roll_epochFree

    Roll all pending breadcrumbs into a new sealed epoch with a Merkle root. Returns { epoch_index, merkle_root, block_count, epoch_hash }. Call this at the end of a session to produce a tamper-evident compliance snapshot.

  • gns_verify_chainFree

    Verify the cryptographic integrity of an agent's breadcrumb chain. Returns { is_valid, block_count, issues[] } plus epoch Merkle roots. A valid chain proves no audit records have been tampered with.

  • perception_classifywrite actionFree

    Run Prithvi-EO-2.0-300M-TL-Sen1Floods11 flood classification on a Sentinel-2 tile previously fetched by perception_fetch_tile. Sends the 6-band chip to a RunPod endpoint and returns: dominant_class, flood_pixel_pct, confidence, class_counts, and the full perception_chain. The perception chain is written to Spatial Memory and a signed audit breadcrumb is dropped to the agent trail.

  • perception_embedFree

    [Sub-phase 4.2 — NOT YET IMPLEMENTED] Will generate Clay v1.5 embeddings.

  • perception_fetch_tileFree

    Fetch the least-cloudy Sentinel-2 L2A tile covering a given H3 cell from Microsoft Planetary Computer. Returns signed COG band URLs for all 6 Prithvi/Clay spectral bands (B02 Blue, B03 Green, B04 Red, B8A NIR, B11 SWIR1, B12 SWIR2), plus tile metadata. The tile is cached in memory for subsequent perception_classify or perception_embed calls.

  • perception_weatherFree

    Query atmospheric conditions for an H3 cell at a given timestamp from Open-Meteo ERA5. Returns wind, precipitation, temperature. Writes to Spatial Memory and drops a signed audit breadcrumb.

🐜 GEIANT

Geo-Identity Agent Navigation & Tasking

The first AI orchestrator that knows where it is.

What is GEIANT?

GEIANT is a geospatial AI agent orchestration runtime built on the GNS Protocol. It is a direct competitor to LangChain, CrewAI, and AutoGen — with one structural difference: every agent has a cryptographic identity bound to an H3 territory, and every task is routed through a compliance enforcement layer before dispatch.

LangChain doesn't know where it is. GEIANT does.

The Ant Metaphor

In GEIANT, agents are ants. Ants are the canonical model of emergent collective intelligence from simple agents following spatial rules. Ant Colony Optimization (ACO) is a real algorithm used in routing and pathfinding. The colony is the orchestrated workflow. The territory is the H3 grid.

  • An ant (AntIdentity) is an agent with a GNS Ed25519 keypair + H3 territory + facet scope + trust tier
  • The colony is a multi-agent workflow where ants delegate and collaborate
  • The nest is the Agent Registry — the directory of available ants
  • The trail is the Virtual Breadcrumb chain — the Proof-of-Jurisdiction audit log

Architecture

L6  Multi-Agent Orchestration    — task graph, delegation chain enforcement
L5  IDUP Settlement Layer        — Stellar payment routing per operation  
L4  MCP GIS Switchboard          — GDAL / PostGIS / ArcGIS / QGIS / EO models
L3  Perception Layer             — IBM Prithvi, Microsoft Clay (EO Foundation Models)
L2  Geometry Validation Layer    — GEOS-backed guardrails, self-intersection detection
L1  Geospatial Router            — H3 jurisdiction matching, TierGate enforcement
L0  Agent Identity & Registry    — Ed25519 + H3 + GNS-AIP (LIVE in gns-node)

Phase 0 (this repo): L0 + L1 + L2 core logic, tests, and API scaffold.

The Four Router Gates

Every task passes through four gates before any ant is selected:

  1. Signature Verification — Ed25519 signature over canonical task JSON
  2. Jurisdiction Resolution — H3 cell → country → regulatory frameworks (GDPR, EU AI Act, FINMA, CCPA...)
  3. Delegation Chain Validation — human GNS identity → delegation cert → scope cells + facets + expiry
  4. Geometry Pre-flight — GEOS-backed validation: self-intersection, coordinate transposition, unclosed rings

Only tasks that pass all four are dispatched. The router is a compliance enforcement point, not a load balancer.

Perception: common questions

Is Perception MCP server safe?
Mostly: it is graded B (76/100). Read the Perception safety report
How do I install Perception?
It runs remotely at packagesmcp-perception-production.up.railway.app. Add it to Claude Code, Cursor, VS Code or Claude Desktop with the snippets above, or call it through the mcp.market gateway without installing anything.
Does Perception need an API key?
Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is Perception maintained?
The last commit was 60 days ago (2026-09-05). The latest release is v0.3.3.
Is Perception up?
100% of our last 28 checks got an answer. We check remote servers about four times a day.
What can I use instead of Perception?
Servers from other publishers that do the same job: Smarter Weather MCP server, Weather Data MCP Server and Weather MCP Server.
How does Perception compare with other Maps and travel MCP servers?
safety score 76/100 (higher than 58% of 681 Maps and travel servers); tools 8 (the typical Maps and travel server has 6); tools that change things 13% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
