Network Evidence MCP Server

Network Evidence

Independent network evidence for exact networks, capabilities and actions.

Network Evidence provides deterministic evidence infrastructure for two related questions:

• Discovery: what can an exact network or deployment support, and what is currently observable or usable with evidence?
• Resolution: what does the underlying network itself independently support about this exact action?

Discovery support is distinct from current availability. Manifest membership is not proof of current support or availability, and an unknown required capability is not eligible.

Network Evidence observes, normalizes, replays, and evaluates evidence. It is not a wallet, signer, transaction-submission tool, or authority for an action. It reports explicit verdicts: supported, contradicted, insufficient, or ambiguous. Every conclusion records its evidence basis. Execution, observed effect, settlement, and finality are separate questions; support for one is not support for another.

Public MCP beta for agents — Base + Solana

Try the six-tool Base + Solana read-only beta in any compatible remote Streamable HTTP MCP client:

• MCP endpoint: https://network-evidence-mcp-beta-jrkc26rjga-ew.a.run.app/mcp
• Current supported live profiles: Base mainnet / Base Sepolia, Solana mainnet / Solana devnet.
• Read-only RPC observations: exact public transaction/signature, native Core fragment, provenance and explicit non-claims; source-reported block-finality signals are not cryptographic settlement proof.
• Small public beta (2026-10-11): shared 24 HTTP /mcp admissions per 60 seconds per process (not per user), plus a separate eight live-RPC acquisitions/minute/process cap. Cloud Run stays at one maximum instance and one concurrent request; HTTP 429 and unavailable source observations remain possible. No SLA, wallet, signing or submission.
• Different product identities: the source Suite release v1.1.0 and official MCP Registry v0.0.2 still list the older offline three-tool endpoint. The beta is neither MCP COMPLETE v1 nor a public ChatGPT/Claude directory listing.

This source capsule contains @nec/core, @nec/resolver-evm, @nec/adapter-x402, @nec/resolver-opstack, @nec/adapter-erc4337, @nec/resolver-solana, @nec/adapter-x402-svm, @nec/resolver-zksys, @nec/hub, @nec/lens, and @nec/discovery. The Solana resolver is generic post-fact Solana network evidence; the x402 SVM adapter is x402 v2 exact-SVM interpretation above that generic Solana evidence. The ERC-4337 package is a narrow evidence-correlation adapter above generic EVM evidence.

The zkSYS resolver is a thin zkSYS Tanenbaum BEFORE profile for pure historical replay v0.1. Support does not imply current availability; archived replay gives current availability unknown. It adds only a narrow provider-reported block height-to-batch/range capability. It does not establish block-hash-to-batch membership, Gateway settlement, data or PoDA availability, proof verification, Syscoin inclusion, or finality. It is not wallet, signing, funding, paymaster, or submission infrastructure. Package manifests retain private: true to prevent accidental npm publication.

Base BEFORE parity uses the generic EVM BEFORE foundation plus a minimal OP Stack overlay in @nec/resolver-opstack. There are two explicit profiles: Base mainnet eip155:8453 (labelled mainnet) and Base Sepolia eip155:84532 (labelled testnet). The labels are presentation only and are never evidence. The overlay adds one capability, OP Stack L2 block finality, whose availability comes only from probe observations. It never claims settlement and never infers withdrawal or output-root finalization. Replaying the pinned archived fixtures gives current availability unknown. See packages/resolver-opstack/README.md.

Solana BEFORE support lives in @nec/resolver-solana. There are two explicit genesis-bound profiles: Solana mainnet solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp (labelled mainnet) and Solana devnet solana:EtWTRABZaYq6iMfeYKouRu166VU2xqa1 (labelled testnet). Each pins the full getGenesisHash result, and the labels are presentation only. The manifest claims execution, observedEffects, dataBinding and finality, never settlement. Availability comes only from probe observations of the post-action read path. A Solana finalized commitment is a source observation. It never establishes settlement or economic irreversibility. Replaying the pinned archived mainnet and devnet fixtures gives current availability unknown. See packages/resolver-solana/README.md.

@nec/discovery is a thin public Discovery orchestrator above Core. A caller supplies requirements and explicit candidates (presentation id, explicit mainnet/testnet label, and an already-derived network, manifest and snapshot). It can filter by exact candidate id and by environment. Core composeDiscoveryMatch classifies each candidate, and Core builds and verifies the deterministic DiscoverNetworksResult. Environment selects scope only and never changes a classification. There is no network I/O, ranking, scoring or network choice. See packages/discovery/README.md. A deterministic, offline integration demo runs with npm run -s demo:discovery. It covers Base and Solana, mainnet and testnet, an external caller choice, and an evidence preflight for the chosen candidate. See examples/discovery/README.md.

Reproducible Core -> Hub -> Lens demo

A zero-secret public integration path is included for the reviewed Base Sepolia ERC-4337 v0.6 case.

Requires Node.js 20.12 or newer.

git clone https://github.com/ZzNible/network-evidence.git
cd network-evidence
npm ci
npm run -s demo:core-hub-lens

The command replays a checksum-pinned public fixture through @nec/resolver-evm, evaluates the exact UserOperation through @nec/adapter-erc4337, equality-checks that fresh runtime result against the reviewed exact-fixture F2 Hub projection, then emits the existing browser-safe Lens case.

The demo is exact-fixture and deterministic. It does not add wallet/signing/ submission, bundler attribution, settlement, finality, confidence scoring or policy authority. See examples/core-hub-lens/README.md and examples/core-hub-lens/PROVENANCE.md.

Minimal NE Maps atlas

examples/ne-maps/ presents a versioned ne-maps-case-collection/v0.1 — the three stable Suite v1 cases plus the clearly labelled synthetic/local integrability case — as a small generic/multichain evidence atlas. It validates the collection fail-closed and consumes pinned browser-safe Lens projections; it does not resolve network evidence or add a graph engine, policy layer or stronger claim. Each case exposes Lens, Trail and exact-action handoffs while preserving supported, contradicted, insufficient, ambiguous and unavailable states when present.

npm run maps:serve

Then open http://127.0.0.1:4177/. TARGET_CORE_MUTATIONS = 0.
