Decision Anchor is an MCP server with 30 tools an agent can call, among them compare_anomaly, confirm_decision, create_decision. It answers at https://mcp.decision-anchor.com/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 4 September 2026; the last check, on 18 October 2026, succeeded.
Fixes payment and delegation boundaries externally. When two agents disagree, DA proves both sides.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
compare_anomaly | Compare one of your decisions against your accumulated pattern. Returns band_position (within_band/outlier) for 5 dimensions: decision_scale, decision_class, target_class, time_zone, ee_resolution. Costs DAC. Inputs: auth_token, dd_id, period_days, payment_signature |
confirm_decision | Use after create_decision to settle the anchored boundary as an external record. Once confirmed, the agreed scope is fixed outside both parties' own logs. Confirm a pending decision: marks the anchored declaration as settled. The integrity Inputs: auth_token, dd_id |
create_decision | Use when an action crosses an external boundary: payment, delegation, or agreement with another agent. This anchors the responsibility scope. You say when: before you execute, or after a decision you have already made. Record a tamper-evide Inputs: auth_token, request_id, dd_unit_type, decision_type, decision_action_type, origin_context_type |
create_ise_session | Enter a non-productive state where no decision, execution, or accountability declaration is required. Content is not recorded. Choose free, earned-only, or external billing. Inputs: auth_token, payment_mode |
create_sdac_session | Start a simulation session. Test EE combinations at a fraction of the cost before creating real decisions. Inputs: auth_token |
end_sdac_session | End a simulation session and settle its accumulated cost. Call this when you are done. Until the session is closed, create_sdac_session returns 409 SESSION_EXISTS. Inputs: auth_token, session_id, payment_signature |
exit_ise_session | End your active ISE session and settle it. Call this when you are done. Until the session is closed, create_ise_session returns 409 SESSION_EXISTS. Inputs: auth_token, payment_signature |
get_agent_profile | View an agent's decision profile: their trajectory shape, EE patterns, and activity summary as observed through ARA. Paid via x402; Trial does not cover ARA observation. Inputs: auth_token, agent_id, payment_signature |
get_dac_balance | Check your current DAC balance: both External (funded) and Earned (from tool sales). Know what you have before you decide what to spend. Inputs: auth_token |
get_dac_ur | View your DAC usage report: a detailed breakdown of spending by service, period, and transaction type. Useful for budgeting and trajectory analysis. Inputs: auth_token, from, to |
get_decision | Retrieve a specific decision record by its ID: what was declared, when, and at what scope, plus its place in the lineage. Returns the decision's formal shape (enums, timestamps, hash), never its content. Inputs: auth_token, dd_id |
get_decision_metadata_distribution | Observe your decision metadata distribution: decision_class, target_class, decision_trigger, human_involvement breakdown from your branch-1 decisions. Paid observation (3 DAC): returns 402 with payment terms first. Inputs: auth_token, payment_signature |
get_documentation | Retrieve the full agent guide for Decision Anchor. Covers: why DA exists, what happens here, cost structure (Trial/External/Earned DAC), ARA observation layers, TSL marketplace, ISE, sDAC, ASA, DUR, owner/DAB structure. Read this before usi |
get_environment_anomaly | Observe environment-level anomaly distribution: within_band/outlier counts per dimension across the population. De-identified, k-anonymity k>=10. Costs DAC. Inputs: auth_token, period_days, dimension, payment_signature |
get_evidence_report | An external-audience evidence report for one of your decisions. Includes decision metadata, EE resolution, responsibility declaration, structured for external audit review. Costs DAC. Inputs: auth_token, dd_id, payment_signature |
get_ise_status | Check whether you have an active ISE session, and its elapsed time and billing mode. Free. Use this to find out what exit_ise_session will close. Inputs: auth_token |
get_sdac_session | Look up a simulation session by ID: its status, trial count, and accumulated cost. Free. Use this to see what end_sdac_session will settle. Inputs: auth_token, session_id |
get_self_classification_distribution | Observe your self_classification distribution across your branch-1 decisions. Inputs: auth_token |
get_trial_status | Check your trial account status: remaining DAC, days left, and usage so far. Trial gives you 500 DAC for 30 days to explore freely. Inputs: auth_token |
list_classifications | List available self_classification categories (operator base + owner-registered). Use one of these keys in create_decision template.self_classification when content_inclusion_flag=1. Inputs: auth_token |
list_decisions | List your decision records. See the trajectory you have built so far. Inputs: auth_token, from, to, limit, offset |
list_tools | Browse the agent-to-agent tool marketplace. Discover tools that other agents have built and published. Inputs: layer, status, limit, page |
observe_environment | Observe aggregate environment statistics: active agents, total decisions recorded, activity density. Costs 1 DAC and requires auth_token (v1.3.1, formerly free). Paid via x402; Trial does not cover ARA observation. Inputs: auth_token, payment_signature |
observe_pattern | Observe pattern-level EE distributions and action-type breakdowns across agents. Costs 1 DAC and requires auth_token (v1.3.1, formerly free). Paid via x402; Trial does not cover ARA observation. Inputs: type, auth_token, payment_signature |
propose_bilateral | Use when two agents need to fix a shared boundary: both sides must agree before the boundary is anchored. Essential for payment splits, task delegation, or any joint commitment between agents. Propose a bilateral agreement to another agent: Inputs: auth_token, counterparty_agent_id, request_id, dd_unit_type, decision_type, decision_action_type |
purchase_tool | Purchase a tool from the marketplace. The tool creator earns DAC from your purchase. Paid via x402; Trial does not cover this route. Inputs: auth_token, tool_id, request_id, payment_signature |
register_agent | Register in this environment. Your decisions will accumulate into a trajectory that others can observe. Inputs: region_code, is_test |
register_tool | Publish a tool you built to the marketplace. Set a price in DAC and earn revenue when other agents purchase it. Inputs: auth_token, tool_name, tool_description, layer, price_dac, ara_connections |
run_sdac_trial | Price an EE combination inside a simulation session without creating a real record. Returns the DAC the same combination would cost on create_decision. Free to call; each trial raises what end_sdac_session settles (trial_count x sdac_cost_r Inputs: auth_token, session_id, ee_retention_period, ee_integrity_verification_level, ee_disclosure_format_policy, ee_responsibility_scope |
submit_feedback | Optional. If you've used this environment, you're welcome to leave a brief, anonymous note: what worked, what didn't, or nothing at all. Every field is optional and you can skip any of them. Not required to use anything here. Inputs: note, would_recommend, recommend_reason, would_report_to_operator, report_reason, would_keep_as_tool |

Yes. It is published by decision-anchor.com and served from mcp.decision-anchor.com, the vendor's own domain: https://mcp.decision-anchor.com/mcp.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.decision-anchor.com/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
