Claude Task Master vs Proof Layer
A side-by-side look at the Claude Task Master and Proof Layer MCP servers: transport, auth, tools, quality signals, and the config to install either one in Claude, Cursor, Windsurf or VS Code.
Verdict: choose Claude Task Master for developer tools work as a local process; choose Proof Layer for cryptography as a local process. You can also run both side by side in one mcpServers block.
Which MCP server should you choose?
Choose Claude Task Master when
- You need dedicated capabilities in the Developer Tools domain.
- You prefer a local stdio subprocess transport.
- Its auth model fits you: API key required.
- You have the keys it needs:
ANTHROPIC_API_KEY, OPENAI_API_KEY, GOOGLE_API_KEY, PERPLEXITY_API_KEY, XAI_API_KEY, OPENROUTER_API_KEY, MISTRAL_API_KEY, TASK_MASTER_TOOLS.
Choose Proof Layer when
- You need dedicated capabilities in the Cryptography domain.
- You prefer a local stdio subprocess transport.
- You have the keys it needs:
PROOF_LAYER_API_KEY, PROOF_LAYER_API_URL. - You want tools like
pl_evaluate, pl_get_receipt, pl_verify_receipt.

Proof Layer tools 8
pl_evaluateSubmit an AI agent action proposal to Proof Layer for governance evaluation. Returns a cryptographically-signed receipt with a verdict of EXECUTE, BLOCK, REVIEW, or SHADOW. Use this before any consequential agent action (sending emails, modifying data, making payments, etc.).pl_get_receiptRetrieve a Proof Layer audit receipt by its UUID. Returns the full receipt including verdict, signature, and policy pack hash.pl_verify_receiptCryptographically verify a Proof Layer receipt. Checks the Ed25519 signature and confirms the signing key is ACTIVE. Returns valid: true/false with a reason.pl_list_receiptsList recent Proof Layer audit receipts for the authenticated tenant. Supports filtering by agent and verdict.pl_usageGet current Proof Layer quota usage — receipts used, receipts remaining, credit balance, billing cycle dates, and plan tier.pl_list_policy_packsList all governance policy packs for the authenticated tenant, including which one is currently active.pl_create_planA human approves a governed plan — a scoped, time-bounded set of future actions across named agents. Returns a plan_id and JTI that agents use to request delegation receipts via pl_delegate. Scope patterns support wildcards: 'build:*' authorizes any action starting with 'build:'.pl_delegateAn agent requests authorization to perform a specific action under a parent plan. Returns 'ok' with a signed receipt (proceed with the action), 'checkpoint_required' (human must re-approve this specific action), or 'denied' (agent or action not authorized under the plan).

Frequently asked questions
Claude Task Master is categorized under Developer Tools and uses a local stdio subprocess. Proof Layer belongs to Cryptography and uses a local stdio subprocess. Pick Claude Task Master for developer tools work and Proof Layer for cryptography.
Copy the mcpServers block from the config section on this page into your client's config (for example claude_desktop_config.json or ~/.cursor/mcp.json), then fully restart the client.
Claude Task Master is bring-your-own-key: usage is billed by the API provider you supply a key for. Auth: api key required. Proof Layer has no declared pricing — check the project's own site. If a server needs environment variables such as API keys, define them under the env key in your client's MCP config.
Yes. MCP clients support multiple servers: add eyaltoledano-claude-task-master and proof-layer as separate keys in the same mcpServers object, and your assistant will call tools from either one.
